Gamla Stan, The Old Town, consists primarily of the island Stadsholmen. The town dates back to the 13th century, and consists of medieval alleyways, cobbled streets, and archaic architecture. North German architecture has had a strong influence in the Old Town's construction. Gamla Stan is one of the best preserved old towns in Northern Europe.
The center of Gamla Stan is Stortorget, the scenic large square, which is surrounded by old merchants' houses including the Stockholm Stock Exchange Building. The square was the site of the Stockholm Bloodbath, where Swedish noblemen were massacred by the Danish King Christian II in November, 1520. The following revolt and civil war led to the dissolution of the Kalmar Union and the subsequent election of King Gustav I.
As well as being home to the Stockholm Cathedral, the Nobel Museum, and the Riddarholm church, Gamla stan also boasts Kungliga slottet, Sweden's baroque Royal Palace, built in the 18th century after the previous palace Tre Kronor burned down. The House of Nobility (Riddarhuset) is on the north-western corner of Gamla stan. The restaurant Den gyldene freden is located on Österlånggatan. It has been in business since 1722 and according to the Guinness Book of Records is the oldest existing restaurant with an unaltered interior. A statue of St. George and the Dragon (sculpted by Bernt Notke) can be found in the Stockholm Cathedral, while Riddarholmskyrkan is the royal burial church. Bollhustäppan, a small courtyard at Slottsbacken behind Finska kyrkan, just south of the main approach to the Royal Palace, is home to one of the smallest statues in Sweden, a little boy in wrought iron. The plaque just below the statue says its name Järnpojken ("The Iron Boy"). It was created by Liss Eriksson in 1919.
From the mid 19th to the mid 20th century Gamla stan was considered a slum, many of its historical buildings left in disrepair, and just after World War 2, several blocks together five alleys were demolished for the enlargement of the Parliament. From the 1980s, however, it has become a tourist attraction as the charm of its medieval, Renaissance architecture and later additions have been valued by later generations.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.
