Enjoy your visit to Prague at your own pace, avoiding long lines for the top 3 sights. Pick up your admission tickets at a central location and let the exploration begin. Each ticket is valid for 2 days from the day it is issued and includes 1 entry to each attraction.  Explore Prague Castle and learn about its history stretching back to the 9th century. Over the years it has been home to Kings of Bohemia, Holy Roman Emperors, and presidents of Czechoslovakia and the Czech Republic. Following Circuit B, explore the highlights of the castle including its beautiful interiors as well as St. Vitus Cathedral, Old Royal Palace, St. George's Basilica, and Golden Lane with Daliborka Tower. Wander on to the Gothic-style Astronomical Clock Tower which has stood the test of time and continues to be one of the most popular attractions in Prague. Before you enter, check out the clock from the outside to see a statue of Christ march out, followed by his disciples. The Grim Reaper also makes an appearance ringing a bell and checking to see whose time has come. 75% of the parts on this clock are original and date back from to the 15th century. With your ticket, enter the Old Town Hall and take the elevator to the tower for panoramic views of Prague's Old Town.  Last but not least, visit the National Museum to discover the Czech Republic's natural history, history, art, and music.
