Planetary astronomical observatory of Anzi, Astronomical observatory and planetarium in Anzi, Italy.

The Planetary Astronomical Observatory of Anzi stands on the summit of Monte Siri in the municipality of Anzi, province of Potenza. Its planetarium has a dome 12 metres across, where about 4,500 northern-sky stars are projected, from Cassiopeia to the zodiac constellations. The observatory holds a Ritchey-Chrétien reflector with a 420 mm primary mirror and 1.5 m focal length on an equatorial fork mount.

The observatory was inaugurated in August 2008 on the summit of Monte Siri, after a medieval crenellated tower that stood on the site was demolished. The astronomical complex is part of a transnational historical route linking eight countries of south-eastern Europe. It is managed by a group of experts recognised by the European Space Agency and Italy's Ministry of Education, Universities and Research.

The complex is part of a transnational historical route linking eight countries of south-eastern Europe, promoted for its natural and cultural heritage. Public events at the site have featured astronauts Paolo Nespoli, Umberto Guidoni and Luca Parmitano, alongside astronomers.

The site is best visited on clear evenings when star visibility is good and observation sessions take place. You should contact the managing association in advance to arrange your visit and confirm participation in a session.

The observatory benefits from its mountainous location, which offers lower light pollution and clearer skies for viewing. This geographic position makes it valuable for professional astronomical observations in the region.
