The highway was great until we got a little ways into the CR. The highway between Dresden and Prague is under construction - a fact that neither the map nor the GPS made us aware of. The signage was OK, though, and we made it to Prague with little trouble.
When we arrived at the city, our first stop turned out to be the city square to get some tourist information and figure out where to park. The square was grand, surrounded by old churches and other buildings. After we got some local funds (CR uses the Korony). Many shops do not accept the Euro), we went up into one of the church towers where we could see the whole city, including the square below and the castle on the hill.
The Prague Castle is the largest in Europe, and includes the St. Vitus cathedral. St. Winceslas is buried in the church, and there are several interesting chapels inside. One of the stories was when the Czechs were being attacked by the Romans (check this), they made loaves of bread in the shape of babies. When the attackers saw them eating the bread, they thought that they were actually eating their babies. Thinking this, the attack was called off, since it was so barbaric that the soldiers couldn't fight.
After touring the castle, we moved down the hill where we found a crowd waiting for the astronomical clock to strike. The church where we initially went up in the tower has a clock that was built in the 16th century (?) that shows the time, phase of the moon, position of the sun, and the sign of the zodiac. Figures come out when the clock chimes the hour. Rather than fighting the crowd, we found a seat at the restaurant across from it. Then we could watch the clock and eat at the same time.
Going home through the construction detour was interesting, as the GPS kept trying to take us back to the non-existent road. A long, tiring day, but it was quite an adventure.
