It was in the Sablon district of Brussels that Patrick Lancz opened his first gallery in 1991. A fervent admirer of the Belgian School, which covers the Symbolist, Impressionist and Fauvist period of the years 1890-1930, he also specializes in Belgian avant-garde of the 1920s and the abstraction of the 1950s-1970s. Patrick Lancz organizes two to three exhibitions a year with the ambition of offering a varied range of artists whose works offer a harmony of techniques and colors while combining old quality framing. The rest of the year, the picture rails of the gallery host various sets that change with the seasons.

The gallery's clientele includes both private and public buyers such as the Musée d'Ixelles, the Royal Museums of Fine Arts in Brussels, the Musée d'Orsay and many international collectors. Patrick Lancz also participates in various international fairs including the Salon du Dessin, Fine Arts Paris & La Biennale and the BRAFA Art Fair. The objective is to present to the public an overview of the riches of Belgian art of the 19th, 20th and 21st centuries: Arthur Craco, Walter Sauer, Léon Spilliaert, Firmin Baes, Théo Van Rysselberghe and many others. In this way, the Lancz Gallery wishes to arouse the curiosity of art lovers and offer them a place of discovery.
