On a hilltop west of the Vltava River, resided what is perceived by many as Prague’s number one tourist attraction – the Prague Castle.
What is called “The Prague Castle” is actually a huge complex of buildings connected by internal courtyards and built throughout the last 1000 years. It therefore provides a great opportunity to visit, in a relatively small location many architectural styles of the last millennium.
An exploration of the castle can take anything between half a day and a full day, depending on how well you want to explore it. The main sights within the Castle are St. Vitus Cathedral, St. George's Basilica, the Royal Palace, the Powder Tower, and of course the Golden Lane in which Frantz Kafka used to live for a while.
If you are interested in doing a little climb up the road, you can certainly walk up directly to the castle from Charles Bridge. Alternatively, it is also possible to use metro line A to Malostranská followed by tram no. 22 north (two stops) to "Prazský hrad".
