The Anenský trojúhelník is a working title for the area marking the end of the so-called Betlémská čtvrť, which lies between the junction of Karolíny Světlé Street and Smetanovo nábřeží, and Anenské and Betlémské náměstí. In recent years, a remarkable project to transform this public space has been underway, involving not only the reconstruction of streets and existing areas but also the creation of a new square at the end of Karolíny Světlé Street.

Anenské náměstí, named after the Anenské Convent of the Dominican Order, which was relocated here in 1313, is one of the city’s oldest public spaces. The space is defined by the facades of a row of significant buildings; in addition to the former convent, these include the Milevských House—historically known as the Na Zábradlí Theater—and, most notably, the northern tip of building No. 208, the Pachtů z Rájova Palace. The square is the intersection of Anenské, Stříbrná, Zlatá, and Na Zábradlí streets. Currently, it serves exclusively as a parking lot. Today, the space is not being used in a manner befitting its significance and location. The new concept is to create a multipurpose space near the prominent buildings of the Pachtův Palace and the Na zábradlí Theater and to regulate parking so that a tranquil area with a fountain, benches, and trees can be established here.

Emphasis is placed on key connections—access to the Na Zábradlí Theater, passage through the arcade to the courtyard of Pachtův Palace, and entry to Stříbrná Street. The project envisions the square being used for occasional events, musical performances related to the Na zábradlí Theater’s repertoire, weekend seasonal markets linked to the program in the courtyard of Pachtův Palace and Jiráskův dům, and more. Given that the Renaissance fountain was moved to Anenské náměstí from Smíchov in 1932 and has never been functional, the proposal calls for its relocation. The type and pattern of paving respect the character of the site. A total of 17 parallel and perpendicular parking spaces will be created.

Historically, this area was an open but paved space along the Vltava River embankment. The river often flooded these areas. Today, the triangular-shaped site in question is a grassy, inaccessible area with trees, bordered by a hedge and self-sown vegetation. The area slopes down from Smetanovo nábřeží toward Karoliny Světlé Street. The proposal involves transforming this previously unused green space into an attractive location in the immediate vicinity of the Vltava River.

The goal of the design is to restore the space connecting to the Old Town—which originally extended all the way to the river—to extend the diverse and mysterious nooks and crannies of the Old Town, and to restore the poetic character of the place using traditional architectural elements—stone paving, staircases, fountains, and understated street furniture.

The new public space is designed on the lower level and opens toward Jiráskův dům, where the sidewalk has been newly widened and the street profile has been adjusted. A tram stop is planned in the upper section on Smetanovo nábřeží. The overall composition is determined by the topography of the terrain; a system of staircases and ramps is being created here to connect the various elevation levels. The concept involves the restoration of a passageway—the “Čapadla,” which was blocked off by construction work in the late 20th century—effectively extending Náprstkova Street and connecting the pedestrian parterre with the Vltava embankment. The goal of the design is to build on the historical legacy of the area, where there was once unobstructed access to the river.

A new elevation and material scheme is proposed for the entire site. A new retaining wall made of stone masonry will be constructed along Smetanovo nábřeží, and the entire area—with the exception of the southern section adjacent to the neighboring building, which will retain its current elevation— will be excavated and leveled with Karoliny Světlé Street, providing unobstructed access to the newly created public space. This space will be paved throughout with Prague mosaic tiles in various patterns corresponding to the individual sections. A new tree is planted within the public space, and a plane tree with a final crown diameter of approximately 20 metres, and roughly halfway across the open space, a fountain is located in the embankment retaining wall; it is designed as a series of water outlets “seeping” from the wall in various segments of the bed joint of the stretcher-bond masonry, with a collection trough running along the retaining wall at the level of the new square.
