Dalhalla

Draggangarna quarry produced limestone until 1990, leaving a hole about four hundred metres long and sixty deep with a lake of green groundwater at the bottom. The opera singer Margareta Dellefors proposed using it as a theatre; the acoustics turned out to be exceptional, with a natural reverberation from the rock walls, and the first performance was in 1993. It now runs a summer season of some thirty concerts across opera, classical and rock, seating around four thousand on terraces cut into the quarry side with the stage on the water's edge. The season is short because there is no roof and the nights get cold quickly.

What you actually see

• A quarry sixty metres deep - with a green lake behind the stage.
• Natural rock acoustics - the reason it works.
• Around four thousand seats - on cut terraces.
• A summer season only - roughly thirty concerts.

When to go

June to August, for a concert. An evening.

Honest expectations

There is no roof - concerts run in rain and it gets genuinely cold after dark. Seats are stone terraces; take a cushion. The descent and climb out are steep. Parking and traffic after events are slow.
