Gatchina Light Night in Gatchina
Gatchina Light Night is described in source data as a light-themed festival in Gatchina, the former imperial residence town south of Saint Petersburg best known for the Gatchina Palace and its Priory Palace. Independent verification found strong evidence of a related, well-documented Gatchina event, Night of Music, but could not confirm a separately established Night of Light under that specific name.
Gatchina holds a distinctive place among the palace towns ringing Saint Petersburg.
