Wroclaw is really one of the most beautiful towns in Central Europe, and the Old Town very much resembles Krakow and Prague - although on a smaller scale, of course, with fewer tourists. Built to commemorate the 100th anniversary of the Battle of Leipzig (hence the German name "Jahrhunderthalle"), the Centennial Hall is quite far away from the centre (I took a taxi to get there and walked back), but is located in a nice, green area near the zoo. There is a small entrance fee to pay, and you can see an exhibition on its construction (interestingly, it was the building whose dome finally surpassed the Pantheon's in diameter), then you are free to walk around the entire building. I was not overly impressed (well, it's a "landmark of reinforced concrete architecture"), but it does make for a pleasant outing in a very nice city, so there is not much to complain about. Today the hall is used for many different purposes, including concerts and even hosting some games in this year's Volleyball European Championships.
