Miramare Castle and its park were built by order of Ferdinand Maximilian of Habsburg (1832–1867). He was the younger brother of Franz Joseph, Emperor of Austria and later the only monarch of the Second Mexican Empire. In 1850, at the age of eighteen, Maximilian came to Trieste with his brother Charles and, immediately afterwards, he set off on a short cruise toward the Near East. This journey confirmed his intention to sail and to get to know the world. He decided to move to Trieste and to have a home built facing the sea and surrounded by a park worthy of his name and rank.
The castle's grounds include an extensive cliff and seashore park of 22 hectares designed by the archduke. The grounds were completely re-landscaped to feature numerous tropical species of trees and plants.
Designed in 1856 by Carl Junker, an Austrian architect, the architectural structure of Miramare was finished in 1860. The style reflects the artistic interests of the archduke, who was acquainted with the eclectic architectural styles of Austria, Germany and England.
On the ground floor, destined for the use of Maximilian and his wife, Charlotte of Belgium, worthy of note are the bedroom and the archduke’s office, which reproduce the cabin and the stern wardroom respectively of the frigate Novara, the war-ship used by Maximilian when he was Commander of the Navy to circumnavigate the world between 1857 and 1859. All the rooms still feature the original furnishings, ornaments, furniture and objects dating back to the middle of the 19th century. Many coats of arms of the Second Mexican Empire decorate the castle, as well as stone ornamentations on the exterior depicting the Aztec eagle.
The first floor includes guest reception areas and the Throne Room. Of note are the magnificent panelling on the ceiling and walls and the Chinese and Japanese drawing-rooms with their oriental furnishings. Of particular interest is the room decorated with paintings by Cesare Dell’Acqua, portraying events in the life of Maximilian and the history of Miramare. Currently, the rooms in the castle are mostly arranged according to the original layout decided upon by the royal couple. A valuable photographic reportage commissioned by the archduke himself made accurate reconstruction possible.
Nowadays to visit the castle is to experience the fascination of life in the middle of the 19th century in a residence that has remained largely intact and which gives the visitor an insight into the personality of Maximilian.
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.
