Originating as an artist-run initiative, PIEDRAS became a gallery in 2018 and, since 2023, has been based in a 400 m² space in Buenos Aires’ San Telmo neighborhood. It represents artists who approach mainstream cultural imaginaries from their edges. Their practices address questions of gender, embodiment, neoliberal economies, and the performative power of fiction in everyday life. The program includes solo and group exhibitions as well as performances, with each project conceived as an open process that emphasizes experimentation and dialogue.

In recent years, the gallery has supported its artists in their first major institutional solo exhibitions, including Mónica Heller at the Argentine Pavilion, Venice Biennale (Italy, 2022); Constanza Giuliani at Kunstmuseum Luzern (Switzerland, 2024); Liv Schulman at Centre Pompidou (France, 2019); Carrie Bencardino at Malba (Argentina, 2025); Josefina Labourt at Centro Cultural Recoleta (Argentina, 2025); and Clara Esborraz (2019) and Carla Grunauer (2021–22) at Museo de Arte Moderno de Buenos Aires (Argentina), among others.

It has also facilitated museum acquisitions in Argentina and abroad, with recent highlights including works by Jimena Croceri entering Harvard Art Museums (US) and MACBA (Spain), and Josefina Labourt entering Denver Art Museum (US). Since 2019, the gallery has maintained a strong presence at fairs such as ARCO, Art Basel Miami Beach, and Liste, known for its focused solo presentations and curated dialogues between two artists.
