The Cathedral of Syracuse (Duomo di Siracusa) origins on this site date to prehistory. The great Greek Temple of Athena was built in the 5th century BC. The temple was a Doric edifice with six columns on the short sides and 14 on the long sides. Plato and Athenaeus mention the temple, and the looting of its ornament is mentioned by Cicero, in 70 BC, as one of the crimes of the governor Verres.
The present cathedral was constructed by Saint Bishop Zosimo of Syracuse in the 7th century. The battered Doric columns of the original temple were incorporated in the walls of the current church. They can be seen inside and out. The building was converted into a mosque in 878, then converted back when Norman Roger I of Sicily retook the city in 1085. The roof of the nave is of Norman origin, as well as the mosaics in the apses.
As part of the increased building activity after the 1693 Sicily earthquake, the cathedral was rebuilt and the façade redesigned by architect Andrea Palma in 1725–1753. The style is classified as High Sicilian Baroque, a relatively late example. The double order of Corinthian columns on the facade provide a classic example of carved Acanthus leaves in the capitals. Sculptor Ignazio Marabitti contributed the full-length statues on the facade.
The interior of the church, a nave and two aisles, combine rustic walls and Baroque details. Features include a font with marble basin dating from the 12th or 13th century, a ciborium (an altar canopy) designed by architect Luigi Vanvitelli, and a statue of the Madonna della Neve by Antonello Gagini (1512).
The cathedral of Syracuse is included in a UNESCO World Heritage Site designated in 2005.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.
