This may not look like a castle but it really is one, Dublin Castle, or better said, one of the courtyards of Dublin Castle. Anyway, the castle of the irish capital city, is not a traditional castle but rather a big fort built by the Anglo-Normans in the 13th century and that over the centuries has undergone some changes.
I've bought a copy of this card the last time I've been to Dublin but this one was sent by Cristina last October.

The castle has served countless purposes since its construction: It was once a military fort, a prison, housed the national treasury, it was a court of law and for 700 years, until 1922, was the seat of the United Kingdom government's administration in Ireland, and is now a major Irish government complex.
The Bedford Tower, built in 1761, is the centerpiece of the Upper Courtyard. It was from there that the Jewels of the Irish Crown were stolen in 1907. The jewels have never been recovered.
