Study your geometry to avoid an embarrassing situation: A triangle pointing down signifies the men’s room (M or Meeste), while the triangle pointing up is the women’s room (N or Naiste).

Visitors with pressing needs won’t be left with their legs crossed, as there are quite a few public toilets around the city. Some can be found at the Viru Gate on Valli (D-5) and there’s a Swedish-built automatic WC on Toompea Hill (B-5), nicknamed locally the ‘million-crown toilet’ due to the public outcry at its construction bill. It can be found next to the Nevski Cathedral (A-5). There’s also a few new high-tech, self-cleaning ones around the city. The most central is right next to Tammsaare Park (D-5), and others can be found at; Toompark near Balti Jaam (A-4), Police Garden (L-7, on Gonsiori street), Kanuti Garden (D-4), Piiskopi Garden (A-5) and in Kadriorg next to the Roheline aas Street parking lot (L-7). However, the fear of being trapped inside may deter the more easily frightened, no matter how badly they need to ‘pee’.
