The Doria Castle of Portovenere is a proper example of Genoese military architecture, even though it has undergone some structural modifications due to the progress of fortifications and firearms. When you first glance at Castello Doria, it looks like one solid piece. But it actually consists of two distinct parts positioned at different levels and enclosed in large Cyclopean walls.
The exact date of construction of the first fortified building is still unknown. Historic documents mention it for the first time in 1139, when the Republic of Genoa took control of the hamlet of Porto Venere. The current castle was built on the remains of the more ancient structure in 1161.
In the 13th century, the castle was at the center of the battles between Genoa and Pisa. It ended up under Nicolò Fieschi’s large fief, to eventually return under the control of the Republic of Genoa in 1276. Major reconstruction works took place between the 15th and 17th centuries, to modernize the castle according to the military and architectonic criteria of the time. At the beginning of the 19th century, during the French rule under Napoleon Bonaparte, the Castello Doria was used as a prison.
Today, this ancient fortress belongs to the Municipality of Portovenere. It underwent a series of accurate restoration works in the 1970s. Apart from welcoming hundreds of visitors for some historic sightseeing and panoramic views of the Bay of Poets, it is also a venue that hosts cultural events, art exhibitions and weddings.
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
