Data from https://en.wikipedia.org/wiki/List_of_castles_in_Ireland
It is said that Irish Castles number more that 30,000. In searching for the number of castles in ruin versus otherwise, there is very little information. Wikipedia offers a list of castles summarized in the table above. The total number of castles shown is 724.

The oldest inhabited castles date back to the 12th century. Most of the castles were built between the 12th and 16th centuries though many continued to be built through the Georgian and Victorian eras.

The reason most often given for the large number is that Irish castles were built for chieftains, of which there were many, and later for Anglo-Norman settlers.

Malahide Castle, County Dublin (2009)
Malahide Castle was built in 1185 by Sir Richard Talbot who was granted the lands by Henry II. It was the home of the Talbots until 1976 when Rose Talbot left it to the Irish State for duties owed. Though from 1649 to 1660, it was in the hands of Miles Corbet after Oliver Cromwell's conquest. Corbet's hanging followed closely on Cromwell's death and it was returned to the Talbots.

On the morning July 11, 1690, fourteen members of the Talbot family sat down for breakfast. That day the Battle of the Boyne was fought between Jacobite forces loyal to deposed King James II, and those of Prince William of Orange and Mary II who ascended to the English throne in 1688. That evening only one Talbot returned to Malahide. Malahide Castle The castle gate with its portcullis.
Powerscourt Estate, County Enniskerry (2009)
While Powerscourt today is considered a Country Estate, it originated as a 13th century Tower Castle built by the Anglo-Norman nobleman La Poer. It's strategic military value was due to its ability to control the nearby Dargle, Glencree and Glencullen Rivers. In the 16th century, it came into the ownership of the Powerscourt family and in the 18th century, Richard Wingfield, 1st Viscount Powerscourt, extensively altered and remodelled the medieval castle to create a modern country house. Mervyn Wingfield, 7th Viscount Powerscourt, in the 18th century created the 47 acre garden. The entire demesne encompasses 77 square miles. Powerscourt viewed from beyond Triton's Lake. Powerscourt includes many fountains including Julia’s Memorial with busts of Michaelangelo and Leonardo da Vinci.
Kilkenny Castle, County Leinster (2009)
Richard "Strongbow" de Clare, 2nd Earl of Pembroke, constructed the first castle in the 12th century. In 1967, Arthur Butler, 6th Marquess and 24th Earl of Ormonde sold the abandoned and deteriorating castle to the Kilkenny Castle Restoration Committee for a ceremonial £50.

Another Damn Castle, County Leinster (2009)
Just one of those 30,000 castles sprinkled through Ireland. I assume that this Tower Castle is abandoned since there is a tree growing out of the center. Another abandoned castle sitting in an open field.
The Rock of Cashel, County Tipperary (2009)
Irish legend says that the Rock of Cashel was created when St. Patrick banished Satan from a cave in Devil's Bit Mountain, a mountain north of Cashel. The Rock was thrown from the mountain and landed in Cashel. The oldest structure on the Rock is the Round Tower dating from around 1100. The Rock was the traditional seat of the Kings of Munster for hundreds of years prior to the Norman Invasion. In 1101, Muirchertach Ua Briain, the King of Munster, donated his fortress on the Rock to the Church. Most of the structures on the Rock date from the 12th and 13th centuries. Unfortunately, the Rock of Cashel was under repair on the day we were there and we had to settle for pictures from a distance.
Yet Another Damn Castle, County Tipperary 2009
With 30,000 castles, it's a wonder I didn't take more of these pictures. No comment.
Blarney Castle, County Cork (2009)
The stone fortification Blarney Castle dates from around 1210. It was destroyed in 1146 but rebuilt by Cormac Láidir MacCarthy, Lord of Muscry. The castle has changed hands many times before being purchased in the early 1700s by Sir James Jeffreys, governor of Cork City. Today, it is famous for the Blarney Stone. To kiss the Stone is to impart the "gift of gab" on the kisser. Legend has it that Cormac Laidir MacCarthy, the builder of Blarney Castle, being involved in a lawsuit in the 15th century, appealed to the goddess Clíodhna for her assistance. She instructed MacCarthy to kiss the first stone he found in the morning on his way to his day in court. He did so and as a result he pleaded his case with great eloquence and won. For luck, MacCarthy incorporated the stone into the parapet of the castle. Blarny Castle, home of the Blarney Stone. To kiss the stone, you must climb to the top of the castle parapet and then, laying on your back, tilt your head back and kiss it. I stayed on the ground and took this picture.
