I have already posted pictures of the Bethlehem Chapel and the Jan Hus Monument, so I will not include them again. The links above will access these photos.
One of the biggest tourist attractions in Prague is the Charles Bridge, which spans the Vltava River and allows access to the Castle from the Old Town. Various street vendors stake out positions on the Charles Bridge to sell their wares to tourists. Here is a view of the Charles Bridge (note the statues that adorn the bridge):The Prague Castle is an important landmark that stands on a hill above the Vltava River and most of the city. Here is a pic of the Castle. Note the St. Vitus Cathedral in the center of the Castle:
above has pictures of one of the monuments in the square. However, the Jan Hus monument is not the only famous structure in the square. The Prague Town Hall sits at the edge of the square and houses an astronomical clock. Hundreds (if not thousands) of tourists mass around the clock near the turn of each hour to observe the clock going off. The clock has doors that open to reveal medieval-looking figures on a turntable, as well as a skeleton on the outside that rings a bell. After all of these festivities, a trumpet belts out a few measures, and the clock is silent for another hour. Here is a pic of me standing in front of the Town Hall.
