Poznan one of the oldest cities in Poland by the Warta River.
Poznan's impressive cathedral is the earliest church in the country, containing the tombs of the first Polish rulers: duke Mieszko I, king Boleslaw the Brave, king Mieszko II, dupe Casimir I the Restorel, duke Przemyslaw I and king Przemyslaw II. Today the city is a vibrant center for trade, industry, and education. Poznań is Poland's 5th largest city and 4th biggest industrial center.
Poznań is known around the world as an important international trade-fair centre. Every year about 30 international and national events are held here. Specialist trade fairs, such as the Polagra Fair, featuring food products, and the Budma Fair, featuring building materials, are among the largest sectoral events in Europe.
The historical landmarks in this city are also well worth seeing. The observation terrace of the Economics Academy skyscraper, 80 m above ground, offers an excellent view of the city's old quarter, Ostrów Tumski, where the cathedral stands today and where once stood the castle of Prince Mieszko I and his son Bolesław the Brave, crowned in 1025 the first king of Poland. Their sarcophaguses can be viewed in the Golden Chapel of the cathedral. Besides gold cups and monstrances from the churches of Wielkopolska, the Archdiocese Museum houses Poland's only painting by Anthony van Dyck.
Poznań's most beautiful church is the huge Baroque Parish Church of St. Stanisław. This is one of Poznań's most mysterious buildings, since parts of the crypts have not yet been investigated. Rumors say that crates of sketches by great Polish painters Jan Matejko and Wojciech Gerson, purchased for the Poznań City Museum just before World War II, were hidden here. Organ concerts are held in the church every day in the summer, with proceeds going to the renovation of the historic organ. Billy goats on the Town Hall The city authorities were housed in the Renaissance Town Hall until 1939, and today the building is home to the Poznań History Museum. At noon two mechanical billy goats clash horns on the Town Hall tower in the middle of the Old Market Square. The fasade of the houses surrounding the square, once the homes of the wealthiest residents, feature Renaissance and Baroque motifs.
