In the Castle Quarter
The finest Gothic structure in Buda - Matthias Church - dates back to the 13th century and was named after the most popular king of Hungary. During the 150-year long occupation of Buda, the Turks used it as a mosque. It is surrounded by the Hilton Hotel (which was built on medieval monastery ruins in the 70s) and the Fisherman's Bastion, which was only ever intended to be purely decorative, rather than protective. Instead, its terraces provide the perfect view over the Pest side. But this grand metropolis isn't only captivating from 180m above sea level – go deeper and explore the underground ‘Hospital in the Rock': a trip to remember.
