Basel is a city in the north-west of Switzerland, located near the borders with France and Germany. The city is located on the river Rhine. The main attraction of the city is the Market Square, on which the 16th-century town hall of red sandstone rises. You can see the city from the observation deck of a 12th-century Gothic cathedral. The cathedral is also known for the fact that the Dutch scientist humanist Erasmus of Rotterdam, who lived in the 16th century, was buried here. Some of the scientist's works are now stored at the University of Basel. The city has a population of 170,000.
