Gamla stan is the old town of Stockholm, Sweden. Gamla stan 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.
Stortorget is the name of the scenic large square in the centre of Gamla Stan, 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.
From the mid-19th century to the early-mid 20th century Gamla stan was considered a slum, many of its historical buildings left in disrepair, and just after World War II, several blocks together five alleys were demolished for the enlargement of the Riksdag. From the 1970s and 80s, however, it has become a tourist attraction as the charm of its medieval, Renaissance architecture and later additions have been valued by later generations.
