Great museum in Wroclaw! As mentioned in the title, it is devoted to the subject of water. Its big facilities include viewing rooms, interactive exhibitions and even a relaxation area. Most of the exhibits include English translation option along with Polish. Lockers do require a zloty coin, but they also have a complimentary cloakroom.
They require tickets in advance, but also have a waiting area. I highly recommend if visiting Wroclaw, Poland. read more
