The gothic Church of St Dominic used to stand west of the Land gate. The first Croatian university mentioned in 1396 was a part of the monastery.
This former church building has had an interesting past. Consecrated in 1280, it belonged to a Dominican monastery who founded the first university in Croatia there (1396). When Napoleon took Zadar in 1805, he abolished the Dominican order, turned the church into a barracks, and shut down the university.

The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
