Reinhold Zisser’s artistic practice is grounded in a process-oriented methodology that understands art not primarily as an object, but as an event shaped by institutional, social, and material conditions. Working within the expanded field of sculpture, his projects unfold through temporal, spatial, and collective processes rather than fixed forms. Zisser treats the conditions of artistic production—curatorial structures, institutional protocols, and socio-environmental contexts—not as external frameworks, but as constitutive material of the work itself.

His practice is informed by traditions of process art and institutional critique, which he extends toward a performative engagement with curatorial and organizational systems. A key example of this approach was the appropriation of the physical body of an abandoned emergency church (Notkirche), which became the basis for his most extensive long-term project, Notgalerie. Conceived as a meta-installation, Notgalerie simultaneously produced both the artwork and the institutional framework within which it operated.

Between 2021 and 2023, Notgalerie evolved into a decentralized and networked sculptural configuration under the working title Notgalerie #Europe. The project unfolded across multiple sites in Austria, Germany, the Czech Republic, Portugal, and Israel, emphasizing connectivity, contingency, and contextual specificity over centralized authorship.

In recent projects, Zisser continues to pursue site-specific and context-responsive strategies, including work in Seestadt and, since 2024, the development of a sculptural pathway in Lower Austria (Skulpturen Plöcking), near Maria Gugging and the Vienna Woods.
