Venue
Ljubljana
Ljubljana and Ljubljana Castle bear witness to the city’s ancient past. A walk to the castle hill rewards you with a magnificent view. If you want to spend a few minutes in peace at the same time, you can escape from the city garden to the beautiful Tivoli Park in the city center. The ancient Roman wall gives an idea of what Ljubljana looked like 2,000 years ago, when the Roman Emona stood here.
