@nytraffittiesogni: There's a subway map hidden in a SoHo sidewalk — and almost nobody notices it 🗺️ A Belgian artist had a crazy idea in 1985. NYC laughed at her. She did it anyway. Nearly 30 meters of steel, concrete and glass discs that light up at night like stars. 📍 110 Greene Street, SoHo. Look down. 💾 Save this for your NYC trip. 💬 Did you know this existed? #NYC #SoHo #NYCHiddenGems #touroperator #NYCSecrets
