The Mound of Down is an ancient monument which gives County Down its name. Originally the home of Celtair - Rath Celtair - this became a stronghold for the Dál Fiatach, a powerful army who once owned the Isle of Man. It is a good example of an Iron Age defensive earthwork in the middle of which a Norman Motte and Bailey was built by John de Courcy after his defeat of Rory Mac Donlevy in 1177.
Originally on the shores of Strangford Lough this site was an excellent military base. The land around has been reclaimed since the 1700s. Today the site is an impressive motte and bailey style fort which was abandoned before completion.
From the top of the incomplete mound you have an excellent view over Down Cathedral and Inch Abbey. In the distance are the Mourne Mountains. During the summer the site is left to grow as a wildlflower meadow.References:
Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
