The Castle was closed to the public. Scaffolding was visible on one side, however, it still is a great photo opportunity. The property lie on the side of the river so you can get some great shots from the bridge. Take the side street on the west of bridge down and you can get right to the edge and see the west side of the Castle up close.
Askeaton isn't that big of a town, it does however house this castle, St. Mary's Church, The Knights Templar Tower, and a fairly well preserved Priory. This isn't the most spectacular castle experience that you will have in County Limerick, but when you add in the other sites available to you in this small town, it's certainly worthwhile to visit.
