The Central Post Office Building ( or Centralposten) is a historical building at 28-34 Vasagatan in central Stockholm, Sweden. Inaugurated in 1903 and designed by architect Ferdinand Boberg (1860–1945), the building was the headquarters of Posten (Swedish post services) until 2003. It is currently serving as offices for the Ministry of Enterprise and some functions of the Government Offices, after an extensive rebuild in April 2008. History The Swedish post services dates back to the 17th century, and its headquarters were during the first 300 years found in various small buildings in Stockholm Old Town. The last building there to accommodate the department was the present Postmuseum, 6 Lilla Nygatan, rebuilt a last time in 1820. However, with the introduction of rail transportation and steamships, increasing quantity of post quickly made the building insufficient. A new central post building was therefore built at Rödbotorget (near today's Sheraton Hotel) to the design of Albert Törnqvist (1819–1898). On its inauguration in the mid-1870s, the new building was well-dimensioned for its purpose, but before the end of the century explosive volumes of postcards had made the headquarters outdated again and in 1896 a decision was taken to move into a larger building. In the mid-19th century, the neighbourhood where the post office now stands, was a rather peripheral district in the centre of Stockholm, a situation which gradually changed with the inauguration of the Stockholm Central Station in 1871. The department's expert advisor, architect F. G. A. Dahl (1885–1927), studied modern post offices in Germany and Belgium and produced plans for a new post office on the site. In late 1897 five Swedish architects — Carl Möller, Ludvig Peterson, Ernst Stenhammar, Eugen thorburn, and Ferdinand Boberg — were invited to participate in a competition for the façades, a competition which Boberg eventually won. The building was inaugurated by King Oscar II on October 27, 1903. It was a modern building for its time; featuring electricity, 58 WC with rings in mahogany, and PO boxes, first introduced in Sweden here. However, long before the inauguration, the site selected for the project had proven insufficient, and in 1915 construction works was started for an enlargement on the remaining third of the block. The building was declared a historical monument (byggnadsminnesmärke) in 1935. A major rebuilding in 1976–78 was followed by several alterations during the 1980s. Three of the four courtyards were glazed-over in 1987–92 resulting
