Stargazing in Brussels, Belgium
Brussels sits in one of Europe's most densely lit regions — the Bortle 8 glow extends across much of Belgium. The Belgian Ardennes (90 minutes south-east) offer the country's best dark skies, reaching Bortle 4 in the more remote valleys. Belgium's maritime climate means frequent cloud, but high-pressure systems from the Azores bring clear spells. The Royal Observatory of Belgium in Uccle has been operating since 1826.
