The Basilica della Santissima Annunziata del Vastato construction was begun by the Franciscans in 1520 in a site previously occupied by the small church of Santa Maria del Prato, belonging to the Humiliati. Works were however halted in 1537, and in 1591 the Lomellini family continued the reconstruction, directed by Taddeo Carlone.
In the early 17th century the rich Baroque decoration was executed, with Andrea Ansaldo in charge of completing the works, and in particular the dome. The current Neoclassicist façade dates to 1830-1840s, designed by Carlo Barabino. The church was damaged by Allied bombings during World War II.
The decoration was employed the major Baroque studios and artists in Genoa in the 17th century.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.
