The Einar Jónsson museum is right next to Hallgrímskirkja church in Reykjavík. It was opened in 1923 and was the first museum in the city at the time it was built and the the only building on the Skólavörðuhæð hill.
The museum was designed by Einar Jónsson himself so it is one of his biggest sculptures. He lived in the house, made his sculptures there and displayed them for guests.
The museum is surrounded by a wonderful sculpture garden that is open all year round. The garden is an ideal place to visit both during the bright and warm summer days as well as the cold winter days when the sculptures get a little extra twist with beautiful snowflakes surrounding them.
