In the 1920s, Margaret Stonborough, sister of Ludwig Wittgenstein, lived at Palais Schönborn-Batthyány in Vienna. During this time, she commissioned the construction of Palais Stonborough, now known as Wittgenstein House, in Vienna’s 3rd district, a project in which Ludwig Wittgenstein played a central role. Palais Schönborn was also the site of the first meeting between Ludwig Wittgenstein and Moritz Schlick of the Vienna Circle.

From 21-27 October 2025, the Wittgenstein Initiative hosted the "WITTGENSTEIN WEEK 2025" in the Beletage of Palais Schönborn, featuring lectures, discussions, and an exhibition.

Ludwig Wittgenstein and Adolf Loos met in 1914, at a time when Wittgenstein was donating part of his inherited fortune to artists and cultural figures. The two appeared to share many common views, and Wittgenstein was pleased by the encounter. Paul Engelmann, who later co-designed the house for Wittgenstein’s sister Margaret Stonborough, had been a student of Loos.

The Werkbundsiedlung in Vienna’s 13th district is a model housing development featuring designs by renowned architects of the time, including Adolf Loos. In 1932, Ludwig Wittgenstein also visited the Werkbundsiedlung. A photograph shows him walking there with relatives (Nedo, 2012, pp. 292–293).

"Don't think, look!"

The "Perspektivenweg" (Path of Perspectives) is a 2.8-kilometre panoramic trail on the Nordkette near Innsbruck, designed by the Norwegian architectural firm Snøhetta. At ten stations, architectural interventions such as platforms and benches invite visitors to pause and reflect. The constructions feature quotes by Ludwig Wittgenstein, selected by philosopher and Wittgenstein scholar Alan Janik.

In Innsbruck, in 1922, a meeting took place between Ludwig Wittgenstein and Bertrand Russell, marking a turning point in their friendship. According to Ray Monk, this was the last friendly meeting between the two. The estrangement was a reflection of a deeper philosophical and personal divergence: Russell remained anchored in the analytical-scientific discourse, while Wittgenstein increasingly turned towards an existential, language-critical, and later, life-practical philosophy.
