Hallstatt Salt Mine

The Habsburg summer residence with 1,441 rooms, formal gardens climbing to the Gloriette and the world's oldest surviving zoo in its grounds.

The Gothic cathedral at the centre of Vienna, with a patterned tile roof and a south tower climbed by 343 steps.

A Baroque palace pair holding Austrian art including Klimt's The Kiss, with a terraced garden between the two buildings.

An eleventh-century hilltop fortress above the old town, reached by funicular, with state rooms and a rampart view over the Alps.

Formal Baroque gardens laid out on axis with the fortress, with hedge terraces, fountains and the steps used in The Sound of Music.

Hallstatt is a lakeside village pressed between a steep salt mountain and the Hallstätter See, with houses stacked along a narrow shelf of land. Salt has been mined above it for more than 3,000 years, and the mine and its funicular are the main reason to go up. The village is very small and receives large day-trip numbers, so early morning or an overnight stay changes the experience completely.
