Alexander Nevsky Cathedral square
Centre ยท ploshtad Sveti Aleksandar Nevski, 1000 Sofia
Sofia's signature landmark, a vast neo-Byzantine cathedral with golden domes that dominate the city skyline. Pets are not admitted inside (assistance dogs only), but the wide stone-paved square outside is leash-friendly and free, with the Saturday flea market spread along the back side. The space stays cool in summer thanks to the surrounding trees.
๐ก Saturday morning at 09:00 for the flea-market loop with a dog โ the square is busiest from 11:00 onward.
