Possessing one of the best-preserved historic city centers in Europe, Prague's narrow laneways open up onto spectacular squares, each home to fine old homes and historical buildings just waiting to be explored.Must-sees include the famous Charles Bridge over the Vltava River, the splendid Jewish Quarter with its old synagogues, and the many historic churches.Unmistakable for its twin 80-meter-tall spires flanking each side of the building (each supporting four smaller spires), its main entrance is through a narrow passage past the houses obscuring its façade.Although completed in the 15th century, the church was altered numerous times through the centuries as the city's allegiances changed, and while interior renovations are ongoing, there's still much worth seeing, including numerous fine tombs, the superb Gothic northern portal with its Crucifixion sculpture, early Baroque altarpiece paintings dating from 1649, and one of Europe's finest 17th-century pipe organs.Founded on the site of a Romanesque rotunda built in 925 AD, the cathedral was started in 1344 and took more than 525 years to complete, resulting in a mix of modern Neo-Gothic and 14th-century Gothic styles, along with Baroque and Renaissance influences.Highlights include stunning stained glass windows depicting the Holy Trinity, a mosaic from 1370 (), and the St.Wenceslas Chapel (Svatovaclavska kaple) with its spectacular jewel-encrusted altar with more than 1,300 precious stones.Also of note, although rarely displayed, are the Czech crown jewels (on average, they're exhibited just once every eight years).
One of Prague's most recognizable buildings is the Church of Our Lady before Týn (Kostel Matky Boží před Týnem), usually abbreviated to simply Týn Church.
Here you'll find the Tyn Church and the Clementinum, along with numerous other fine old churches, as well as splendid old architecture dating back as far as the 11th century, while the Jewish Quarter, Josefov, is just a short walk north.
A highlight is the Old Town Hall (Staromestská radnice), home to the wonderful early 15th-century Astronomical Clock (orloj): each hour, it springs to life as the 12 Apostles and other figures appear and parade in procession across the clock face.
English language guided tours are available, and for a truly memorable experience, the Clementinum is also used as a venue for jazz and classical concerts.
The historic center of Prague, the Old Town (Staré Město), is where you'll find the splendid Old Town Square (Staroměstské náměstí), one of the best places to begin exploring the city.
