The city of Sibiu was one of the most important fortified cities in Central Europe. Multiple rings were built around the city, most of them out of clay bricks. The south-eastern fortifications are the best kept, and all three parallel lines are still visible. The first is an exterior earth mound, the second is a 10-meter-tall red brick wall, and the third line comprises towers linked by another 10-meter-tall wall. All structures are connected via a labyrinth of tunnels and passageways, designed to ensure transport between the city and lines of defense.
In the 16th century more modern elements were added to the fortifications, mainly leaf-shaped bastions. Two of these survived to this day, as the Haller Bastion (all the way down Coposu Boulevard) and “Soldisch Bastion”.
 Passage of the Stairs
The steep Passage of the Stairs leads down to the lower section of Sibiu. It descends along some fortifications under the support arches. It is the most picturesque of the several passages linking the two sides of the city.
Sibiu is one of Romania’s most culturally lively cities. It has 3 theatres and a philharmonic orchestra.
The Radu Stanca National Theatre is one of the leading Romanian theatres. With origins dating back to 1787, it attracts some of the best-known Romanian directors, such as Tompa Gábor and Silviu Purcărete. It has both a Romanian-language and a German-language section, and presents an average of five shows a week.
The Gong Theatre is specialised in puppetry, mime and non-conventional shows for children and teenagers. It also presents shows in both Romanian and German.
The State Philharmonic of Sibiu presents weekly classical music concerts, and educational concerts for children and teenagers. The concerts take place in the newly restored Thalia Hall, a concert and theatre hall dating from 1787, situated along the old city fortifications. Weekly organ concerts are organised at the Evangelical Cathedral during summers, and thematic concerts are presented by the Faculty of Theology choir at the Orthodox Cathedral.
