This interactive museum is an exceptional place to gain a deeper understanding of Warsaw’s history. It was founded in commemoration of an event that profoundly changed the city: the Warsaw Uprising of 1944. Listen to the oral accounts given by insurgents, go down into the sewers — similar to the ones that insurgents used to move around the city — and see The City of Ruins, a bird’s-eye view of Warsaw burnt to the ground. Don’t forget to see the murals painted by Polish artists on the Wall of Art. The museum building is interesting in its own right since it was previously an old electric power plant for trams.

Walking tours are great options if you want to quickly orient yourself in a new city within 2–3 hours and meet a couple of fellow travellers. Your Viking guide will make sure you don't walk past any hidden gems and tell you stories of the Vikings, elves and modern-day Icelanders. Some tours might include lunch, others — booze. It's up to you how to stay warm.
