At the end of the 17th century, the Dominican Order established a monastery in Aglona and built the first wooden church. After the church burnt down in 1699, a stone monastery building and the present church were built in its place in 1768-1780. The interior of the shrine was created in the 18th-19th century, but the pulpit, the organ, and the confessional were built at the end of the 18th century.
The church houses an extensive collection of paintings, sculptures, and artistic treasures, including the famous icon “Our Miraculous Lady of Aglona”, which is uncovered only during religious festivals. The painting is considered to have healing powers. In 1993, Pope John Paul II visited Aglona sanctuary. Extensive renovation works in the church and improvements of the surrounding amenities were carried out prior to this visit.
Every year on the 15th of August, pilgrims congregate in Aglona to mark the day of the Assumption of the Virgin Mary into Heaven.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.
