The Doge's Palace was once the home of the Doges of Genoa. It is now a museum and a centre for cultural events and arts exhibitions. It is situated in the heart of the city, with two different entrances and façades, the main one on Piazza Matteotti, and the second one on Piazza De Ferrari.
The first parts of the Palace were built between 1251 and 1275, during the flourishing period of the Republican history of Genoa, while the Torre Grimaldina (also named 'Torre del Popolo') was completed in 1539.
The palace originated from the acquisition by the commune of Genoa of houses of the Doria between San Matteo and San Lorenzo churches (1291), after which the construction of an annexed new building was started. To this, in 1294, a tower of the Fieschi family was added. The palace was restored in the 1590s by Andrea Ceresola. Around 1655, the Ducal Chapel was frescoed by Giovanni Battista Carlone and Domenico Fiasella. In 1777, it was subject to a fire, and was subsequently rebuilt in Neoclassicist style by Simone Cantoni.
On the main floor, the so-called Piano Nobile, are the frescoed halls of the Maggior and Minor Consiglio, where many public events take place.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.
