Most tourists walk past this beautiful Art Nouveau building on Tverskaya Street without noticing. It's a former monastery building hidden in a courtyard so you have to actively look for it.

Walk along the main Tverskaya street near Tverskaya metro. Entrance through courtyard - look for detailed ironwork and decorative facades of this historic income-generating house.

Visit during daytime for photography. The ironwork details are incredible if you're into architectural photography or just appreciate craftsmanship.
