SAP Arena is a multi-purpose arena in Mannheim, Germany. It is primarily used for ice hockey and handball, and is the home arena of the Adler Mannheim ice hockey club and the Rhein-Neckar Löwen handball club. Inaugurated in 2005, the arena has a capacity of up to 15,000 people. More than a hundred concerts and congressional events are hosted at the arena annually. The SAP Arena is one of the largest in Germany and one of the most high-tech in Europe. The arena is named after its sponsor SAP. A tram line (number 6) connects the SAP Arena to Mannheim city center and a newly built road connection to the B 38a highway connects it to the A 656 Autobahn, leading to the A656/A 6 interchange, connecting eastbound Mannheim to Heidelberg (A656), and north/southbound to Frankfurt, Karlsruhe and Stuttgart (A6), as well as a little north on the A6 to Kaiserlautern (westbound).
