We explore Prague this morning, one of Europe’s most impressive capitals, thanks to its grand squares, imposing Charles Bridge, Old Town, charming Astronomical Clock in the Old Town Square and Prague Castle, perched high above the city and reckoned to be the largest ancient castle in the world. The castle is a magnificent complex that has served as the seat of power for Czech kings, emperors and presidents. We enjoy entrance to the castle, its interior rich in art and historic artefacts.
