Horní Lumbeho zahrada, Private garden in Hradčany, Prague, Czech Republic.

Horní Lumbeho zahrada is a private garden in Prague's Hradčany district, sloping south from Jelení Street toward Nový Svět. Its western boundary is a staircase from Keplerova Street down to Černínská, and its eastern boundary is U Brusnice Street, which separates it from the lower Lumbeho garden with the Lumbeho Villa and Prague Castle's production greenhouses. The plot is part of the Prague Castle complex; most belongs to the Castle Administration, part is private.

The garden takes its name from the Lumbe brothers: the surgeon and politician Karel Lumbe owned the villa, while his brother Josef Lumbe, an agricultural expert and politician, bought the surrounding gardens. Under the communist regime, the Upper Lumbe Garden was used as an allotment colony for employees of the Ministry of the Interior and Defence. Today most of the land belongs to the Prague Castle Administration, with part in private hands.

The lower part of the garden, entered from the Nový Svět lane, holds a wooden summer theatre stage and a children's playground. The grounds were once a gardeners' colony for Ministry of Interior and Defence staff under the communist regime, and most of the land now belongs to the Prague Castle Administration.

The lower section includes a children's playground reachable from Nový Svět street. Visitors should expect varying elevation changes as the garden covers sloping terrain.

The garden's western edge is formed by a staircase running from Keplerova Street down to Černínská Street. Looking east from it, the silhouette of St. Vitus Cathedral rises beyond the slope, a view of the castle that walkers on the street below do not get.
