AIDS-Hilfe Potsdam has worked on HIV and sexual health in the city since 1991 and covers the rest of Brandenburg as well. The office is on Hebbelstraße, a quiet residential street a few minutes north of the centre.
What it offers someone passing through: HIV and STI testing, information and advice on PrEP, and counselling that can be anonymous. There is support for people living with HIV, separate men's and women's groups, and advice for anyone who has run into discrimination. Home test kits are available too. Counselling in person is by appointment, and the phone line takes calls without one.
It also runs an outdoor programme for queer men called Raus unter dem Regenbogen. A guided walk goes out into the countryside around Potsdam once a month and there are cycling trips, both open to anyone who turns up.
The organisation coordinates the Brandenburg initiative for sexual health and education, so it is the point of contact for the whole state rather than just for Potsdam.
