dc.description.abstract	We have observed Lyngå 7, previously catalogued as an open cluster, in B, V and I.The Colour Magnitude Diagrams (CMDs) show that it is old like a globular cluster, or an extremely old thick/old disk cluster. It has a red horizontal branch and the CMD morphology indicates that it is metal rich, intermediate between 47 Tuc and NGC 6553. We derive a reddening of E(B – V) = 0.72 and a distance of ≈ 6.7 kpc from the Sun. Its position in the Galaxy shows that it should belong to the metal-rich disk system of globular clusters, being close to its edge.	en
