Korsholm Castle was a medieval castle in Vaasa. It was probably built in the 1370s and the oldest record dates back to 1384 (the testament of Bo Jonsson Grip, where the castle was called as Krytzeborg). The castle was originally built to a small island and it was surrounded by a moat and two walls. The castle itself was probably built of wood.
In the Middle Ages Korsholm was a property of several nobles. The most famous of them was Sten Sture the Older. In 1748 the new governor house was built to the site and all medieval structures were demolished. The next house was built in 1851 but it was destroyed by the great fire of Vaasa in 1852. Today a low mound is all that remains of the castle. There is also a monument dedicated to the castle.References:
Stavanger Cathedral is Norway's oldest cathedral. Bishop Reinald, who may have come from Winchester, is said to have started construction of the Cathedral around 1100. It was finished around 1150, and the city of Stavanger counts 1125 as its year of foundation. The Cathedral was consecrated to Swithin as its patron saint. Saint Swithun was an early Bishop of Winchester and subsequently patron saint of Winchester Cathedral. Stavanger was ravaged by fire in 1272, and the Cathedral suffered heavy damage. It was rebuilt under bishop Arne, and the Romanesque Cathedral was enlarged in the Gothic style.
In 1682, king Christian V decided to move Stavanger's episcopal seat to Kristiansand. However, on Stavanger's 800th anniversary in 1925, king Haakon VII instated Jacob Christian Petersen as Stavanger's first bishop in nearly 250 years.During a renovation in the 1860s, the Cathedral's exterior and interior was considerably altered. The stone walls were plastered, and the Cathedral lost much of its medieval looks. A major restoration led by Gerhard Fischer in 1939-1964 partly reversed those changes. The latest major restoration of the Cathedral was conducted in 1999. Andrew Lawrenceson Smith is famous for his works here.
