According to the contract of 1254 between Saare Lääne bishop Heinrich and the High Master of the Order Eberhard von Seyne the diocesan area of Hiiumaa was divided into two parts and Käina became the center of one of them. In the middle of the 13th century a new house of God was built in the newly established parish. The building´s incinerated ruins were discovered in 1981 while clearing the nave of the church.
A stone church was erected here in 1492-1515 during the reign of Saare-Lääne bishop Johannes III Orges. It is one of the youngest and quaintest medieval sacral buildings in the Western Archipelago, a simple gothic church with a single-aisle nave. Between the years 1859-1860 Käina church was thoroughly rebuilt. The southern wall of the nave was torn down and the nave was extended with a large new added structure in the southern side of the church. At first the church´s saint was Saint Nicholas, later however Saint Martin.
On October 14, 1941 the church was hit by an incendiary bomb which, dropping in through the ceiling of the choir burned the building to the ground.
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.
