In Berlin, you can find many different kind of museums. This one is dedicated to the LGBTQ+ community. Although the museum isn't huge, it still holds usually 3-4 exhibitions. And most of them will display for quite some time, sometime even a year, so visitors have enough time to plan their visit. They also have free tour with English and German, if you want to join, I recommend to have a look on their official website, there are more information about it.
I just visited not long ago, the admission cost 9 euro per person now (regular ticket), well, not cheap, but I think of it as a support to the local LGBTQ+ community. If you are student, you will get a discount, but take your stiuden ID with you. The employees are also quite friendly and helpful there.
At the moment, the main theme in the museum is transgender, quite interesting and glad there is a platform for them, so they can to be seen and heard. If this is not topic for you now, just wait for the next exhibition. I think, this museum is one of a kind, you can learn more about the people from LGBTQ+ community, their life, history, culture, art and more.
