Clontarf Castle, Co. Dublin

Clontarf Castle is a much-modernised castle, dating to 1837, in Clontarf, Dublin, Ireland, an area famous as a key location of the Battle of Clontarf in 1014. There has been a castle on the site since 1172. In modern times, it has functioned as a bar, cabaret venue, and hotel. The first castle on the grounds, of which no trace remains, was built in 1172 by either Hugh de Lacy, Lord of Meath, or his tenant Adam de Phepoe. Clontarf was subsequently held by the Knights Templar and, after their suppression in 1308, passed to the Knights Hospitaller, until they were in turn deprived of it at the Dissolution of the Monasteries. The last prior, John Rawson was created Viscount Clontarf in 1541 in return for surrendering the castle and its lands to the crown. 16th century to 17th century In 1600 Queen Elizabeth I granted the estate to Sir Geoffrey Fenton, her secretary of state for Ireland, and it passed by marriage from his descendants to the King family. George King of Clontarf took part in the Irish Rebellion of 1641 and as a result his lands were confiscated.

Roscommon Castle is located on a hillside just outside the town. Now in ruins, the castle is quadrangular in shape, it had four corner D-shaped towers, three storeys high, and twin towers at its entrance gateway, one of which still retains its immensely sturdy vaulted roof. The entire castle was enclosed by a lofty curtain wall. It was built in 1269 by Robert de Ufford, Justiciar of Ireland, on lands he had seized from the Augustinian Priory. The castle had a most chequered history. It was besieged by Connacht King Aodh Ó Conchobhair in 1272.Eight years later it was again in the hands of an English garrison, and fully repaired. By 1340 the O’Connor’s regained possession of it, and, except for a few brief intermissions, they held it for two centuries until 1569, when Sir Henry Sidney, Lord Deputy seized it. It was granted to Sir Nicholas Malbie, Elizabethan Governor of Connaught, in 1578. Two years later the interior was remodelled and large mullioned windows were inserted in the towers and curtain walls. Again, in 1641 the Parliamentarian faction gained it until Confederate Catholics under Preston captured it in 1645.It remained in Irish hands until 1652 when it was partially blown up by Cromwellian “Ironsides” under Commissary Reynolds, who had all the fortifications dismantled.

The visitor center has displays that explain the park as well as an audio-visual show and is accessible for patrons with disabilities. It was designed by John Townsend Trench, a cousin of its builder and first owner, John George Adair, with whom he had been raised in Co. Laois.

The building stone chose was granite, plentiful in Donegal but difficult to work and allowing for little detail.

Howth Castle, Co. Dublin

And Estate is situated just outside the village of Howth, County Dublin Ireland, in the administration of Fingal County Council. The castle was the ancestral home of the St Lawrence family.

On the grounds near the castle there are golf, pitch and putt and foot golf courses, a period hotel, formal gardens and a pond, rhododendron trails and several small streams running through the grounds. In October 2018, the family announced their agreement to sell the castle, estate and Irish Eye to investment group Tetrarch. They wanted to convert the hotel and golf course into a luxury resort. Tetrarch sold a 7 hectare portion of the property earmarked for residential development near Castle Gate to Glenveagh Homes for €14million on completion of the sale.

Johnstown Castle is located on the Johnstown Castle Estate, a 150 acres (61 ha) estate, located off the road between Murntown and Rathaspeck, 5.5 km (3.4 mi) southwest of Wexford town. The first castle built on the estate was a tower house built in the late 12th century by the Esmonde family, Normans who came to southeast Ireland from Lincolnshire in the 1170s after the Norman invasion of Ireland (1169). They also built a tower house, which still stands, at Rathlannan immediately to the south. Oliver Cromwell spent a night on the estate in 1649, prior to the October 1649 Sack of Wexford. His Roundhead army used the land around Johnstown Castle to prepare. The Esmondes, Catholics, were expelled during the Cromwellian years. Johnstown Castle was bought by the Grogan family in 1692. Owner Cornelius Grogan was hanged for his part in the 1798 Rebellion; he had been commissary-general for the United Irishmen. In 1810 the estate was restored to his brother John Knox Grogan, who, with his son, Hamilton Knox Grogan-Morgan, created Johnstown Castle as it stands today, on the “bones” of the Norman tower house.

Doe Castle, Co. Donegal

Nestled in an inlet of Sheephaven Bay in County Donegal , skirting the wild waters of the Atlantic, stands Doe Castle – the medieval stronghold of the MacSweeneys. The fortress was built in the 1420s. For almost 200 years it served as home, refuge and bastion for at least 13 MacSweeney chiefs – some of whom were party and witness to the most seismic events of Irish history. For example, MacSweeney chief Eoghan Og II gave shelter to survivors of the 1588 Spanish Armada fleet at Doe. The last chief of the castle, Maolmhuire an Bhata Bhui, marched out with Red Hugh O’Donnell, lord of Tyrconnell, to the Battle of Kinsale in 1601.

Belfast Castle, Co. Antrim

One of Northern Ireland’s most famous landmarks. Sitting in a prominent position in Cave Hill Country Park, we have spectacular views out across the lough and the city. The first Belfast Castle was built by the Normans in Belfast city centre in the late 12th century. A second castle, made of stone and timber, was later constructed by Sir Arthur Chichester, Baron of Belfast, on the same site in 1611. Sadly, the castle burned down almost 100 years later, leaving only street names, such as Castle Place, to mark its location. Donegall Period In 1862, the third Marquis of Donegall, a descendant of the Chichester family, decided to build a new castle within his deer park, situated on the side of Cave Hill in what is now north Belfast. Designs for the new building were completed by architect John Lanyon and reflected the popular Scottish baronial style. The castle was finished in 1870 and cost far more than the £11,000 set aside by the Marquis. In order to complete the building, he received financial help from his son-in-law, Lord Ashley, heir to the title of Earl of Shaftesbury. Shaftesbury Period When the third Marquis of Donegall died in 1884, the castle and its estate passed to Lord Ashley, the seventh Earl of Shaftesbury.

Lismore Castle, Co. Waterford

Lismore Castle has a rich and varied history, owned or visited by some of the most notable names of the last few centuries — Sir Walter Raleigh, Fred Astaire, J.F. Kennedy, John Betjeman, Cecil Beaton, Dominic West, Lucian Freud. Earls, dukes and other royals; soccer stars and rock stars — the list is almost as long as Lismore’s history. The first owner was the soon-to-be King of England, Prince John, when he built Lismore back in 1185. On becoming monarch, he passed it to the Church to be used as a Bishop’s Palace — you can still see the old round tower, which dates back to the 13th Century. Then Sir Walter Raleigh, the Elizabethan adventurer who introduced tobacco to the English court, bought the castle. But 13 years later he was imprisoned for high treason in the Tower of London, and so Lismore, along with its 42,000 acres, got sold to Richard Boyle for a sum of £1,500. Richard later became the first Earl of Cork, and his son Robert Boyle, who was born at Lismore, became the philosopher that many consider the father of modern chemistry. As time passed, the lands passed to the fourth Duke of Devonshire. This was in 1753, after the Duke married Lady Charlotte Boyle, the heiress of the Earl of Cork.

Dromoland Castle, Co. Clare

Donegal Castle, Co. Donegal

In the very heart of the county town, towering over the River Eske, stands Donegal Castle. Red Hugh O’Donnell himself built it as his personal fortress in the fifteenth century. It is said that, leaving to seek succour in Spain in the wake of the Battle of Kinsale, Hugh determined to make sure his castle would never ever fall into English hands – by setting it on fire. But he was to be disappointed. English captain Sir Basil Brooke became the castle’s new lord in 1616. As part of a massive programme of improvements, Brooke built a handsome manor house beside the tower. He also commissioned the magnificent chimney-piece, finely decorated with carved fruit and his own imperious coat of arms.

Carrigogunnell Castle, Co. Limerick

Situated near Clarina, this castle is superbly situated on a volcanic rock with a marvellous view overlooking the whole Shannon estuary. It consists of a multi-sided enclosure, fortified by a strong wall probably of 15th-century date, in a poor state of preservation. The ruins of Carrigogunnell Castle dominate the lovely pastoral land surrounding the volcanic peak on which it was built mid 15th century on the site of an earlier structure. The shattered limestone Keep was once over 50 feet high with 5 stories and a spiral stair, and there was a later house adjoining the tower with additional buildings, all fortified by a strong wall. The land had been granted by King John to Donchad Cairbreach O’Brien in 1209 and had been a very important stronghold of the O’Briens for centuries. It was destroyed following the 1691 siege of Limerick — although the garrison sheltered by the castle took no part in the actual siege and surrendered without a fight, the English did not need the castle so they destroyed it with a large quantity of gun powder, attesting to the sad shape that it is in today.

Malahide Castle and Gardens, Co. Dublin

King Henry II gifted Richard Talbot the lands and harbour of Malahide for his services to the crown in 1185. From that point on, the Talbot family became intertwined with Malahide’s history and development. The original stronghold built on the lands was a wooden fortress but this was eventually superseded by a stone structure on the site of the current Malahide Castle. Over the centuries, rooms and fortifications were added, modified and strengthened until the castle took on its current form. The Talbots are reputed to have been a diplomatic family and during the eight centuries between 1185 and the 1970s, their tenure at Malahide Castle was broken for only a brief interlude between 1649 and 1660 when their lands were seized by Cromwellian soldiers and the castle was occupied by Myles Corbet, Lord Chief Baron of Ireland. The final Baron de Malahide, Lord Milo Talbot, lived in the castle until his death in 1973. His sister Rose inherited the estate and subsequently sold it to the Irish State in 1975. Since then, Malahide Castle has continued to play an important part in Ireland’s political and social landscape, hosting international leaders and summits, and welcoming thousands of local and international visitors each year.

Clogh Oughter Castle, Co. Cavan

Prehistoric relict landscapes of Cavan Burren Within the Cavan Burren Park there are more than 50 hut sites and over 10km of prehistoric walls. Incorporated within these settlement features are over 150 boulder monuments – 100 having either Rock Art and/or Rock Sculptings. The boulder monuments, rock art and sculptings are mostly incorporated in the walls and may be regarded as all more or less contemporary with the settlement features. Based upon existing evidence these are probably contemporary with the Giant’s Leap Wedge Tomb.
