We arrived when it was pleasantly empty… which quickly explained itself
Most of the museum was closed, but you can still walk around the grounds and see the historic buildings from the outside, which is actually quite nice and peaceful.
Even without access to the interiors, it’s a pleasant stroll and gives you a good sense of old Reykjavík architecture. Not a must-see if everything is closed, but still worth a quick stop if you’re nearby and want something calm and low-key
