Trim Castle (Caislean Bhaile Atha Troim) – Located in the historically rich Boyne Valley in the center of the town of Trim,County Meath. Its the largest and best preserved Anglo-Norman castle in Ireland.

It was surrounded by 500 m of walls and a moat, its area was 30,000 m2 and the whole area is 1.2 hectares.

This construction from the 12th century was built in thirty years on the place of the wooden fortress by Hugh de Lacy, but he unfortunately did not see the completion of construction because he was beheaded, his son Walter completed the construction and was built as the seat of Lord Meath

This castle is also called King John Castle, although he spent only two or three days here.
As a curiosity, it is worth mentioning that in 1995, Mel Gibson chose this place for recording scenes for Braveheart and it was thanks to this movie that Trim was finally noticed.
The castle was opened to the public only in 2000 after a long period of renovation.
