Estonian islands, located a short ferry ride from mainland, have many old churches and crumbling fortresses left behind by pagan Estonian warriors, German knights and Soviet military. You can bike, walk or drive along the dusty rural roads passing stretches of coastline. Also the 19th-century lighthouses and old windmills are worth of seeing.
Maasi medieval fort-castle was built with the forced labour of islanders. That's how the ruling Liivi order punished indigenous inhabitants for the uprising, which had destroyed orders previous stronghold. Seaside fort-castle was undefeated until destroyed by Danes. The fortress was blown up in 1576 by the Danes in an attempt to forestall the Swedish invasion and nothing was done for the next 300 years. 8m walls that survived the destruction have become a landmark.
Dejevo village was established during the Soviet era. There were several missile bases and garrisons around the village. After soldiers left and missiles were hauled away, the village was totally abandoned. In 2011 most of the brick and concrete buildings on the surface were demolished.
There has been a windmill park in Angla about hundred years. Five of the original nine windmills still remain, most of them built in 1920’s. One of them is a Dutch-style windmill with turnable tower.
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
