The Salvador church was erected on the remains of the Ibn Adabba, the Great Mosque of Muslim Seville (9th century). This religious temple, as well as its surroundings, had great importance in the daily life of the people, which is why when the Christians conquered Seville, they allowed it to be used as a mosque in the beginning, but in 1340, it was converted into the parish of Salvador.
In addition, it was agreed to maintain the ostentatious rank of the second temple of the city; for it was granted a collegiate character. Thus, this building would continue to be used religiously until 1671, when the passage of time left it strongly deteriorated. Its construction as we see it today began in 1674 with the architect Esteban García. Work ended in 1712 under the architect Leonardo de Figueroa.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.
