Ljubljana Summer Festival

The Križanke Outdoor Theatre (Poletno gledališče Križanke) is a theatre in Ljubljana, Slovenia, used for summer festivals set up inside the courtyard of the former Monastery of the Holy Cross. It is located at French Revolution Square (Trg francoske revolucije) no. 1. It was created by Jože Plečnik in the 1950s within the confiscated former monastery especially for the Ljubljana Festival and the Secondary School for Design and Photography. Ljubljana Festival holds major events on the open-air stage, while other venues include the Baroque-style Križanke Church, the Knights' Hall (Viteška dvorana) and the Devil's Courtyard (Peklensko dvorišče). The amphitheatre-like southern courtyard with its large retractable canopy has since proved to be a superb venue for classical, jazz, and rock concerts. The venue is managed by the Festival Ljubljana Public Institute and is available for hire. The part of the former monastery premises, which is occupied by the Secondary School for Design and Photography, is used to host students interested in photography, graphics design, fashion, industrial arts and an art gymnasium. Because of the lack of space the school is also based on another location, on Roška cesta 2.

The building is considered one of the greatest achievements by Plečnik. According to the Mandatory Publications Copy Act, issuers are bound to submit a copy of each publication they publish to the National and University Library. In 2011, the library kept about 1,307,000 books, 8,700 manuscripts, and numerous other text, visual and multimedia resources, and was (in 2010) subscribed to 7900 periodicals. Books and other resources are kept at storehouses at Auersperg Street (Turjaška ulica) and at Leskošek Street (Leskoškova cesta). There have been significant problems with a lack of space and a new modern building has been planned to be built in the vicinity.

Zois Mansion (Slovene: Zoisova palača) is a mansion in Ljubljana, the capital of Slovenia. It stands in the Center District, at Breg, a street on the west (left) bank of the Ljubljanica, between Teutonic Street (Križevniška ulica) to the north and Zois Street (Zoisova cesta) to the south. The mansion served as residence of Baron Sigmund Zois, a leading figure of Enlightenment in the Slovene Lands of the Austrian monarchy and supporter of the revival of Slovene culture and literature.The mansion was built between 1765 and 1805, combining until 1770 four older buildings, and then in 1805 another one. The facade was redesigned in the neoclassicist style in 1798. The monumental stone portal dates to 1589 and was made by the manson Abondio di Donino for the building of the town warehouse. It was redesigned in the 18th century, except for the keystone that has been built into facade left of the main entrance. It bears a relief of the coat of arms of the town that has also been ascribed to Donino. Right of the main entrance, there is a bronze bust of Sigmund Zois from 1993, work by the sculptor Mirsad Begić. In the mansion's yard stands an old fountain. Zois's tombstone is etched into the wall facing the yard.Between the 1780s and the first decade of the 19th century, the mansion was used as the venue of the Slovene intellectual elite, which included the playwright and historian Anton Tomaž Linhart, poet and journalist Valentin Vodnik, philologists Jurij Japelj and Blaž Kumerdej, and linguist Jernej Kopitar.

Emona (early Medieval Greek: Ἤμονα) or Aemona (short for Colonia Iulia Aemona) was a Roman castrum, located in the area where the navigable Ljubljanica river came closest to Castle Hill, serving the trade between the city's settlers – colonists from the northern part of Roman Italy – and the rest of the empire. Emona was the region's easternmost city, although it was assumed formerly that it was part of the Pannonia or Illyricum, but archaeological findings from 2008 proved otherwise. From the late 4th to the late 6th century, Emona was the seat of a bishopric that had intensive contacts with the ecclesiastical circle of Milan, reflected in the architecture of the early Christian complex along Erjavec Street in present-day Ljubljana. The Visigoths camped by Emona in the winter of 408/9, the Huns attacked it during their campaign of 452, the Langobards passed through on their way to Italy in 568, and then came incursions by the Avars and Slavs. The ancient cemetery in Dravlje indicates that the original inhabitants and invaders were able to live peacefully side by side for several decades. After the first half of the 6th century, there was no life left in Emona. The 18th-century Ljubljana Renaissance elite shared the interest in Antiquity with the rest of Europe, attributing the founding of Ljubljana to the mythical Jason and the Argonauts. Other ancient Roman towns located in present-day Slovenia include Nauportus (now Vrhnika), Celeia (now Celje), Neviodunum (now the village of Drnovo) and Poetovio (now Ptuj).

St. James's Bridge (Slovene: Šentjakobski most) in Ljubljana is a bridge that crosses the Ljubljanica River on the southern end of downtown Ljubljana, next to Zois Manor.
