There was originally a Roman castellum (Castellum Laurum) in Woerden, as part of the limes of the Roman Empire and thus part of the defense lines of the northern border of the Roman Empire. The first castellum was built in the 40s AD, and was destroyed in 69 AD during the Batavian rebellion. In 70 AD the castellum was rebuilt, and the Romans remained until 402 AD, with an interruption lasting from about 275-300 AD. The Castellum was located at the present site of the medieval Petruschurch and surrounding church yard. During construction work on a new underground parking facility in the city center of Woerden, the remains of numerous old Roman buildings and a Roman cargo ship were found.
The current castle was built in around 1160 by bishop Godfrey van Rhenen. Due to its strategic location on the border between the County of Holland and the Bishopric of Utrecht, various wars have been fought in and around Woerden. In 1410 John III, Duke of Bavaria-Straubing reconstructed the castle.
Until the 19th century the castle was used as a prison. There's even a pit prison in the northwest tower, which was used for unruly prisoners. In the 20th century the castle was part of military barracks and used for storage of all kinds of goods but poorly maintained. This caused severe decay. Today it is restored as a restaurant.References:
The Old Town in Aarhus, Denmark (Den Gamle By), is an open-air town museum consisting of 75 historical buildings collected from 20 townships in all parts of the country. In 1914 the museum opened as the world's first open-air museum of its kind, concentrating on town culture rather than village culture, and to this day it remains one of just a few top rated Danish museums outside Copenhagen.
The museum buildings are organized into a small town of chiefly half-timbered structures originally erected between 1550 and the late 19th century in various parts of the country and later moved to Aarhus during the 20th century. In all there are some 27 rooms, chambers or kitchens, 34 workshops, 10 groceries or shops, 5 historical gardens, a post office, a customs office, a school and a theatre.
The town itself is the main attraction but most buildings are open for visitors; rooms are either decorated in the original historical style or organized into larger exhibits of which there are 5 regular with varying themes. There are several groceries, diners and workshops spread throughout the town with museum staff working in the roles of town figures i.e. merchant, blacksmith etc. adding to the illusion of a 'living' town.
