In my opinion there are several reasons why people visit museums if they visit a new city.
The first reasons is, that every bigger town has museum and as a result you do not have to think about where to go first. For example if you would visit Berlin you will first think about which places to visit and will select probably a museum near your place.
Another aspect is learning something about the history of the place. Because if you are in a unfamiliar place, you like to get to know the history and traditions for example.
Further visiting museums always leads to new knowledge. Very often you read something new, not only specific for the place itself but also in general. This particular knowledge helps you to improve understanding the surroundings of this place.
In conclusion visiting a museum does have a lot of positive aspects and if you have the time just choose a museum which sounds interesting, there always will be a benefit for you.
