There is a local red light district in the East of Frankfurt, two minutes walk from Konstablerwache, based around Breite Gasse (Gasse is similar to way).
The red light district around Breite Gasse is very small compared to the more well known Frankfurt red light area of Bahnhofsviertel (Station Quarter) and has about four or five brothels grouped on one corner.
There is also an adult cinema and a sex shop in the vicinity.
Breite Gasse, as a sex tourist attraction in Europe, hardly rates, because it caters to local clientele and regular customers.
The area around it looks a bit dodgy; immigrants can be seen lounging around, for what, no-one has really figured out, or really wants to know.
The brothels of Breite Gasse in the East of Frankfurt can be seen in another light – they service the local area, and the businesses and prostitutes prefer the quiet location and lack of action, as compared to the buzz one finds in the Bahnhofsviertel; international and European travellers, drug addicts, misfits etc.
Frankfurt’s bygone past as an entertainment destination for off-duty American soldiers (when their US Dollars where actually worth something) has long gone, and all that remains are pieces of history, some are still functioning businesses but catering to a more demure market and clientele.
