Built to celebrate Mohamed's spiritual journey, this imposing Mosque is open to visitors of all faiths. More sober than the Dome, it was built in an early Islamic style; however, due to its complicated history, it features elements from different art styles, such as Romanesque arches, Corinthian columns, and Italian marble. The Mosque used to host the King of Jerusalem and the Templar Knights during the Crusades era.

Situated at the end of Andrássy Avenue, Heroes' Square is one of Budapest's most iconic landmarks. Dominated by the Millennium Monument, it pays homage to Hungary's history and leaders.

The easiest thing to do is rent a snorkel and explore the shallow waters by the beach, but you should definitely consider trying something more advanced at least once. Snorkelling is the cheapest choice. Add some diving equipment to go deeper and see more. Some tours now offer Sea Trek helmets — a modern take on the diving helmet. No matter your choice of equipment, do explore the coral reefs that are home to tropical fish such as snapper, hamlets, parrot fish, sturgeon, squirrel fish and majestic sea turtles.
