Kastelholma Castle

Sund, Finland

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. The castle started to decay and was used only as prison until it burnt down in 1745 and was finally abandoded in 1770.

Kastelholma is one of only five surviving Finnish medieval fortresses. Nowadays it is a major tourist attraction easily accessible by car or bus from Mariehamn. Excavated items, such as early stove tiles, are on exhibit in the hall. A medieval festival, replete with dance, food, and jousting occurs each year in July. The area around and down to Stornäset has become a royal estate with a golf course also available in the area.

This Castle is amazing! If you visit Åland Islands this is a must to visit. The Scandinavian history is built into these stone walls...

Lovely place even outside the main season when the buildings are not accessible (at least during our visit (saturday, late october) they weren't). The place is very well kept and strolling around the peaceful grounds learning history was a blast. Will definitely recommend checking this gem out!

Very interesting castle to visit if history is your thing. It's not that well preserved but there's still some originality left so you still can get the historical view of the place. Admission fee also covers the small prison museum a couple of hundred metres away. It's also worth the visit.

Very pleasant and historical place to visit. Worth to see in Åland. There are also headsets to listen the historical story of this castle. Not sure how it is, however the views and sign posts tell enough for travelers. Don't forget to visit the prison and Jan Karlsgården around this place. For hungry people there is also a place to eat very cool food. Local lamb and some salmon soup. Go for it

Okey place, but there is not much to see inside and there is only very little information. Also it is only castle here so basically must see. At the end there is room where kids can play with some swords, shield, helmets and costumes. There is even little chainmail for the kids to wear. Most kids seem to love these few simple items so might be well worth of 8 euros entrance fee for adults and 5 euros for kids. Smallest kids go for free.

Seaplane Harbour Museum

The Seaplane Harbour is the newest and one of the most exciting museums in Tallinn. It tells stories about the Estonian maritime and military history. The museum’s display, that comprises of more than a couple of hundred large exhibits, revitalizes the colourful history of Estonia.

British built submarine Lembit weighing 600 tones is the centrepiece of the new museum. Built in 1936 for the Estonian navy, Lembit served in the World War II under the Soviet flag. It remained in service for 75 years being the oldest submarine in the World still in use until it was hauled ashore in 2011. Despite its long history, Lembit is still in an excellent condition offering a glimpse of the 1930s art of technology.

Another exciting attraction is a full-scale replica of Short Type 184, a British pre-World War II seaplane, which was also used by the Estonian armed forces. Short Type 184 has earned its place in military history by being the first aircraft ever to attack an enemy’s ship with an air-launched torpedo. Since none of the original seaplanes have survived, the replica in Seaplane Harbour is the only full-size representation of the aircraft in the whole World.

Simulators mimicking a flight above Tallinn, around-the-world journey in the yellow submarine, navigating on the Tallinn bay make this museum heaven for kids or adventurous adults.

Seaplane Harbour operates in architecturally unique hangars built almost a century ago, in 1916 and 1917, as a part of Peter the Great sea fortress. These hangars are the World’s first reinforced concrete shell structures of such a great size. Charles Lindbergh, the man who performed the first solo flight across the Atlantic Ocean, landed here in 1930s.

On the outdoor area visitors can tour a collection of historic ships, including the Suur Tõll, Europe's largest steam-powered icebreaker.
