We associate a canonical unital involutive quantale to a topological groupoid. When the groupoid is alsoétale, this association is compatible with but independent from the theory of localicétale groupoids and their quantales [9] of P. Resende. As a motivating example, we describe the connection between the quantale and the C * -algebra that both classify Penrose tilings, which was left as an open problem i
