Goslar is a town in Lower Saxony.
Goslar was founded in 922 AD by the Saxon German Emporer Henry I. although it is widely assumed that there had been a settlement since pre-roman times. The town is famed for its magnificient gates and ramparts, the mediaeval Imperial Palace, its half timbered guild houses, the ancient Rammelsberg ore mine, ... and its witches, the last of which has been burned at stake in 1657 AD. In the mediaevial times the city had been a major producer of armoury, the raw ores for their manufacture came from the Rammelsberg mine just outsite the city's walls.
Essentially Goslar was an Imperial City, which came under direct control of the Emporer and there were no regional feudal overlords, who were in charge of the city until the end of the Thirty Year War. Thus the city's citizens were largely left to their own devices, since the Emporers had mostly better things to do then to sit in their Imperial Palace at goslar, as there were plenty more Imperial Palaces where they could riside. The only problem was that the city's craftsmen had to lease the rights to the mine from even such a regional overlord, the Duke of Brunswick. This inevitably let to clashes between the two parties, which were not solved until the end of the Thirty Year War in 1646 with the Goslar Accord.
Since the Reformation Goslar has escaped the interest of the emporer, and its riches declined. That is why the City is so uniquely preserved that it holds UNESCO World Heritage Status.
Goslar is the Harz regions festival town, with the annual award of the "Imperial Ring".
