With a caveat:
Brunswick, Germany
About
With a caveat: Bruchstrasse [12] is Braunschweig's red light district. Referred to as Gurke (gherkin or cucumber) by locals, this area is off-limits to minors and "non-working "women (women are likely to be subject to harrassment and verbal abuse through prostitutes when walking down this street), and shielded from public views by two iron gates. It has an interesting historic side to it though, since it is one of the oldest red lights districts in Germany, maybe in the world (prostitution in this part of town was documented as early as 1594), featuring some Medieval-style timber-framed houses, which can be seen from outside the gates.
