The Stagemobil L is a very popular stage type for small and medium sized events on market places and town squares. You can choose between a 30 or 42 m² set-up.
Here, you get a fully covered stage which is suitable for most events at the city center squares. There is, for example, room for a 7-man rock band, 30 singers or a 15-man bigband.
