The Czartoryski Museum houses a vast collection of ancient works of art from Greece and Egypt, but the key artworks here have to be Leonardo Da Vinci’s "Lady with an Ermine” and Rembrandt’s “Landscape with the Good Samaritan”.

This is one of the few surviving parts of the ancient defence system that once surrounded the Old Town. Built in the early 14th century, it was the main defence of the north. Further towers were added in the 15th century, but the Florian's Gate is the only remaining gate from the original eight. In 1660, it was extended to include a Baroque roof, raising its height by one metre, and today it measures around 33.5 metres.

The onyx black sand of Reynisfjara is formed from volcanic activity in Iceland: when lava collides with the ocean, it rapidly cools and shatters into small fragments of basalt. With its enormous basalt stacks (features in Game of Thrones and once believed to be petrified trolls), roaring Atlantic waves and stunning vistas, Reynisfjara is widely considered to be the most beautiful example of Iceland’s black sand beaches. The sea stacks along the shore are home to thousands of nesting seabirds like puffins, fulmars and guillemots — a must-see for birdwatchers. A visit to Reynisfjara is included in most tours of southern Iceland. Driving here is a good option, too, since it's only about 180 km from Reykjavík.
