The Old Town forms the historic center of Heidelberg. The Heidelberg Castle, which lies on the 567.8-meter-high Königstuhl mountain, can also be found here. You can either reach the mountain via the so-called “Himmelsleiter”, or alternatively take the cable car up to enjoy a wonderful view of the Necker valley. Heidelberg Castle also houses the world’s largest actively used wine barrel, which can hold up to 220,000 liters. The buildings of the Old Town are mainly from Baroque times and the rental prices in Heidelberg’s Old Town are therefore higher than in other parts of the city. Hotel prices are also higher here. If you are traveling to Heidelberg on business for more than a month, you should consider booking an alternative accommodation, such as a furnished apartment.
