The Hamburg Rathaus is the Rathaus—the city hall or town hall—of Hamburg, Germany, it is the seat of the government of Hamburg, located in the Altstadt quarter in the city centre, near the lake Binnenalster and the central station. Constructed from 1886 to 1897, the city hall still houses its original governmental functions with the office of the First Mayor of Hamburg and the meeting rooms for Hamburg's parliament and senate (the city's executive). After the old city hall was destroyed in the great fire of 1842, it took almost 44 years to build a new one. The present building was designed by a group of seven architects, led by Martin Haller. Construction started in 1886 and the new city hall was inaugurated in 1897. Its cost was 11 million German gold marks, about €80 million. On October 26, 1897 at the official opening ceremony the First Mayor Dr. Johannes Versmann received the key of the city hall. From Wikipedia, the free encyclopedia
