Drimnagh Castle is of norman origins dating back to the 13th century and was one of the oldest continually inhabited castles up until the 1950's when it was bought by the christian brothers - a religious community  who have educated thousands of Irish pupils over at least the last 100  years and still own the castle and the school and lands surrounding it.

It is also one of the few if not the only castle in Ireland that still retains a fully flooded moat around it's walls. Other features of this wonderful little gem of a castle - not to mention its history which you can hear more about from the knowledgeable tour guides working there are its formal garden, oak wood roof, murder hole, arrow slit windows, an enormous fireplace, sculpture and supposedly the ghost of a young woman who still haunts the building and environs. It  was recently beautifully restored using traditional methods as faithful to original designs and materials of the times of its original construction - but most of what you see is the real deal.

Not many people are aware of this little oasis of history and calm in the greater Dublin area - it is worth a visit, you won't be dissapointed. To get there from the city centre take a bus to Drimnagh say the 77, 56a and ask the bus conductor to let you off at the the village near the halfway house pub/long mile road, cross over to the opposite side of the road from where you alight (there should be a petrol station on that side to help you get your bearings) facing away from the direction you've come from on the bus, proceed up the long mile road, straight ahead where there is a fork in the road (do not take the left road that the bus takes) and continue for about 300 metres until you come to the gates of a school - go in and continue to the back of the school following the black tarmacadam road and you will see the castle. Not sure what the fee is nowadays but it should not be more than 5 or 6 euro.
