A really beautiful place, but until further notice, no entry. Very nice security, even allows drone flights.

A Caisleán / O'Briens Castle Caisleán Uí Bhriain (O' Briens Castle) was built in the 14th century. It was built within an older ring fort called Dún Formna, which is thought to date from 400 BC. As well as fantastic views of the island, there are also magnificent views from the Cliffs of Moher, stretching to the left to the Burren, across Galway Bay to the 12 Pins of Connemara and to the west to Inis Meáin and Inis Mór. On a fine day you can even see the Kerry Mountains in the distance. It's worth taking your camera, especially for a spectacular sunset. The castle is a rectangular keep built by the O'Briens. They were a clan from County Clare who ruled the islands and large parts of Clare in the Middle Ages. From this castle they were able to control the shipping routes to Galway and are said to have operated protection rackets there. Due to its strategic location the castle was the subject of numerous competing interests. It was captured by the O'Flahertys around 1582 and was in use until it was supposedly captured and destroyed by Cromwell in 1652. The original entrance led to the first floor and was accessed via an external wooden staircase. Inside there was a hall taking up the whole of the first floor with an internal staircase in the SW wall leading up to the parapets. The ground floor was originally a basement with three vaulted chambers accessed from the first floor. Look out for the corbel of a watchtower which survives on the external wall and has a human face carved into it. The original Dún Formna has been restored a number of times throughout its history. It dates from the same period as the more famous Dún Aonghasa on Inis Mór and probably contained some clocháns, of which no trace remains today. (Source: https://www.rothai-inisoirr.com/an-caislean/)

Some may know the action film "Blast Command Atlantic", where Dunguaire Castle served as a film set. From the car park it is only a 3-minute walk to Dunguaire Castle, which is called Caislean Dún Guaire in Irish. A large signpost on the side of the road ensures that you cannot miss your destination and you can also see this sight from a distance.
