The Dorëzi Fortress is the oldest in the Tirana county and dates to the 9th century BC. The first archaeological expedition was performed in 1951. The ruins of the fortress are to be found in one of the highest hills of the Krrabë, at about 479 metres above sea level. It is thought that Dimale may have been situated in the Dorëzi Fortress.
The surrounding wall is in its southern part, and is 300 metres long from east to west. The fortress construction seems to have had three phases—the first with raw stones, the second with carved blocks placed with no mortar (Hellenistic period) and the third with crushed stones and the use of mortar (4th–6th centuries AD). One can see the main entrance of the fortress. The presence of old vases that date to those centuries suggests that the site was inhabited until at least the 4th–6th centuries AD.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.
