Iron Fountain, Gyumri, Armenia

Not sure if you can consider this brutalism, but it definitely passes the vibe check. The fountain was built in 1982, and stood at the entrance to the Polytechnic University campus, but a devastating earthquake in 1988 destroyed the entire campus, and the fountain is the only surviving structure. The fountain was designed by architect Artur Tarkhanyan, who also designed the Zvartnots International Airport in Yerevan (also worth a visit, but the security can make taking photos there an extreme sport!).
