2. Ljubljana Castle

Tour Ljubljana Castle (Ljubljanski grad), an iconic city landmark and a place to discover centuries of Slovene history. Perched atop the wooded Castle Hill, the castle rises above Ljubljana’s medieval Old Town with a mishmash of defensive walls, towers and turrets. Much of the complex dates to the 16th century but evidence suggests that there has been a castle here since the 12th century. In its long history Ljubljana Castle has served as a garrison, prison and royal residence.

3. Piazza Unita d'Italia

Piazza dell’Unità (or Piazza dell'Unità d’Italia) is a huge sea-facing square and a magnificent accomplishment of civic pride. Once a location for extravagant processions and celebrations, today a combination of landmark architecture and cultural events continue to make it the city’s pulsating heart. Designed by Giuseppe Bruni, Piazza dell'Unità is enclosed on three sides, with one open side looking out over the Gulf of Trieste. Visit the square to appreciate its architecture, attend concerts and enjoy people-watching opportunities.

Stroll across the bridge, appreciate its craftsmanship and admire its decorative statues. The bridge opened to the public in 1901 and was originally known as the Jubilee Bridge of Emperor Franz Joseph I. It replaced an old wooden bridge and is one of Europe’s earliest examples of a reinforced concrete bridge.
