Built in the 19th century in gothic revival style by Prosper Morey, Saint-Epvre’s Basilica is decorated with stained glass and wood panelling and was in-part made in Bavaria. It was richly endowed by Napoleon III, Emperor Franz-Joseph, Ludwig II of Bavaria and Pope Pius who donated the beautiful stone paving in the choir that came from the Appian Way.
The market square and general trading centre in the Middle Ages, the fountain in the middle has a statue of Duke René II of Lorraine, who defeated Charles the bold, Duke of Burgundy, at the Battle of Nancy in 1477.
References: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.
