Located on the right bank of the Tiber River, guarding one of Rome's oldest bridges, the Castel Sant'Angelo is an imposing cylindrical building, initially commissioned by Emperor Hadrian as a mausoleum for himself and his family. It was later converted into a fortress, a papal residence, and a prison. Now, it's a museum offering beautiful views of Rome.

Located in the heart of the city, this museum of fine arts provides visitors with a unique opportunity to stroll through the historic surroundings of an Augustinian monastery and marvel at its impressive collection of sculptures and paintings from the Middle Ages to the early 20th century.

On the waterfront, only a few minutes from Harpa sits the most famous sculpture in Iceland, the Sólfarið or the Sun Voyager. Made of steel and resembling a Viking ship — although this was not the artist's intention — the Sun Voyager is, according to its creator Jón Gunnar Árnason, an ode to the sun, a dreamboat symbolising the promise of undiscovered territory, the dream of hope, progress, and freedom. This is also one of the best spots for a picture in Reykjavík, with Mount Esja providing the perfect backdrop.

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.
