The pool has always been very popular, but after the renovations it has even gained more popularity among locals and guests.
Sundhöllin Reykjavíkur is the oldest thermal pool in Iceland, first opened 1937 with an indoor thermal pool. Later hot tubs and a sauna were added. It was designed by the noted architect Guðjón Samúelsson. The building's exterior is a minimalistic white with tall narrow rectangular windows.
It is located right in the heart of Reykjavik, only a few minutes walk from Hallgrímskirkja church and open every day.
