1 Charles Bridge Built in 1357 for the Holy Roman Emperor Charles IV, the bridge straddles the Vltava River and connects the Old Town with Mala Strana. During the day the bridge bustles with activity. Street musicians compete with artisans hawking jewellery, paintings and Bohemian glass trinkets. There may be a crowd around the statue of St John of Nepomuk, a Czech saint martyred when he was thrown off the Charles Bridge into the Vltava River during the reign of King Wenceslas IV. People queue to touch the statue for good luck. Legend has it that egg yolks were mixed into the mortar to strengthen the bridge, which has survived many floods, including the torrents of August 2002, which amounted to Prague's worst in 500 years. 2 Astronomical clock The 15th-century astronomical clock is Prague's central meeting point and a distinguishing feature of this architecturally stunning city. Each hour, crowds gather beneath the clock to watch the models of apostles appear in its windows. The clock has two round faces: an impressive circular disc that measures the time and shows the movement of the sun around the Earth, and below it, a calendar with paintings of Czech rural life by Josef Manes. 3 Vrboska Zahrada This baroque garden is an architectural gem built on a steep hillside and is secreted behind high walls in Karmelitska Street in Mala Strana. Its Italian-style terrace garden was built in 1715 for Jan Joseph, the Earl of Vrtba. The gardens are terraced and each level is supported by curved walls and connected to the next by sweeping staircases. The lower part of the garden has an aviary and a neat circular pool surrounded by islands of trimmed hedges. Throughout the various levels can be found frescoes, statues, sculpted hedges, scenic walls and sweeping staircases. The view over Prague changes as you ascend each level of the garden. At the top, the garden narrows, and there's a seat where you can sit to admire the spires, domes and rooftops. 4 Prague Castle This ancient castle, which dates from AD880, has been the seat of the Czech government since Prince Borivoj founded the first fortified settlement on these grounds. The castle sits on a hill dominating the skyline and qualifies as the largest ancient castle in the world. History and architecture merge to make Prague Castle an awe-inspiring symbol of ancient splendour. You can spend days wandering through the castle's serene halls and palatial quarters. 5 Old Town Although this is the throbbing heart of Prague's tourist activities, with rows of restaurants and quaint shops, the Old Town manages to retain a dream quality, with horse-drawn carriages, colourful street performers and buildings that resemble a movie set. A maze of interesting side streets leads out of Prague's old town square. You can stroll for hours admiring the architecture and browsing shops. There are many stalls that sell puppets, dolls, original paintings of Prague and cast-iron souvenirs. At night, the buildings are lit up like a Bohemian fairyland and provide an enchanting backdrop for Prague's many evening outdoor concerts. 6 John Lennon's Peace Wall Tucked away in a quiet square amid the baroque architecture of Prague's diplomatic quarter, you'll find John Lennon's Peace Wall. Although Lennon never visited Prague, he was admired as a pacifist hero by Czech youth. After Lennon was murdered in 1980, young locals covered a wall in a city square with peace-inspired graffiti and portraits. In the following decade, the wall became a gathering place for those opposing the communist regime and the oppression it represented. Even though the government continually painted over the wall, Lennon's portrait would always reappear. Lennon's face, surrounded by anti-totalitarian graffiti, is still there, left alone by the new regime. 7 Jewish Quarter A recent addition to the World Heritage list, the Jewish Quarter has a rich history dating from the 10th century. At the time, Jews lived below Prague Castle in what's now the Lesser Quarter. Their community grew to form a Jewish Town - with its own representative authority, court system and extensive autonomy - that was divided from the Christian town by a wall. Reforms by the emperor Josef II helped to ease living conditions. The Jewish Quarter contains the remains of Prague's former Jewish ghetto, which was once the largest Jewish settlement in Europe. Sights worth visiting are St Procopius' Basilica (built as part of the Benedictine monastery in the early 13th century), the Old-New Synagogue (Europe's oldest working synagogue) and the Old Jewish Cemetery (Europe's oldest surviving Jewish burial ground). The cemetery has thousands of crumbling stones on as many as 100,000 graves. 8 St Nicholas' Church Prague has many elaborate baroque churches designed to impress the common folk with the power and richness of the Jesuit faith. They come complete with original statues and ceiling frescoes. St Nicholas' Church took 80 years to complete and has so many statues it could take an afternoon to explore. Mozart tinkled on the ivories of the church's 2,500-pipe organ. 9 Bohemian crystal Bohemian crystal glass artwork originated in the 17th century, when Italian and German cutters joined the court of King Rudolf II and began to cut the natural crystal found throughout Czech territories. Bohemian crystal became well known around the world, but attempts to imitate it were unsuccessful until English lead crystal appeared. In today's Prague you can buy beautiful vases, wine glasses, plates, bowls, decanters and other glassware in both traditional and contemporary glass designs. 10 Vltava River The Vltava River flows from the southern border of the Czech Republic through the centre of Prague to its northern border. It divides the city into two - the eastern bank, where the Old Town is located, and the western bank, where Prague Castle stands. Enjoy the views of Prague's skyline lit up against the night sky as you glide along the Vltava River past the castle, the Vysehrad area and the National Theatre, while tucking into a three-course buffet dinner. Another way of enjoying the river is to stay at the Riverside Hotel on the western bank of the Vltava River, just two bridges from Charles Bridge. This boutique hotel has an Art Nouveau facade and is decorated in belle epoque style, with luxurious custom-made furnishings. Most rooms offer fairytale views of the city's towers and turrets.
