The construction of Põltsamaa Castle was started in 1272. Between 1570 and 1578 it was the residence of Livonia's King Magnus. Repeatedly pillages, the castle was rebuilt by Woldemar Johann von Lauw in 1770 as a grand rococo-style palace. The castle, and the church built into its cannon tower, burnt down in 1941.
Põltsamaa St. Nicholas' Church was built from 1632 to 1633 on the site of earlier buildings. The nave was built on the 13th century gate buildings and the sanctuary on the 15th century cannon tower. The church was restored by 1952, and the castle ruins came under preservation during the 1970s.
Today the round courtyard holds a tourist information point and several museums including Põltsamaa Museum and a wine cellar with a food museum. There are also an art gallery, restaurant, handicraft and other workshops.
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.
