The Dome of the Rock is an Islamic shrine located on the Temple Mount in the Old City of Jerusalem. It was initially completed in 691 CE at the order of Umayyad Caliph Abd al-Malik during the Second Fitna, built on the site of the Roman temple of Jupiter Capitolinus, which had in turn been built on the site of the Second Jewish Temple, destroyed during the Roman Siege of Jerusalem in 70 CE. The original dome collapsed in 1015 and was rebuilt in 1022–23. The Dome of the Rock is in its core one of the oldest extant works of Islamic architecture.
Its architecture and mosaics were patterned after nearby Byzantine churches and palaces, although its outside appearance has been significantly changed in the Ottoman period and again in the modern period, notably with the addition of the gold-plated roof, in 1959–61 and again in 1993. The octagonal plan of the structure may also have been influenced by the Byzantine Church of the Seat of Mary (also known as Kathisma in Greek and al-Qadismu in Arabic) built between 451 and 458 on the road between Jerusalem and Bethlehem.
The site's great significance for Muslims derives from traditions connecting it to the creation of the world and to the belief that the Prophet Muhammad's Night Journey to heaven started from the rock at the center of the structure. The rock also bears great significance for Jews as the purported site of Abraham's attempted sacrifice of his son.
It has been called Jerusalem's most recognizable landmark, and it is a UNESCO World Heritage Site, along with two nearby Temple Mount structures, the Western Wall, and the 'Resurrection Rotunda' in the Church of the Holy Sepulchre.
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.
