Here beats the heart of Athens! Ermou Street is the most commercial street in the capital and at the same time one of the most expensive in Europe and worldwide. Fair got its name from the messenger of the gods and protector of Mercury commercial, along the stretch of shops, cafes, and restaurants. Pedestrian for the most part, Ermou Street starts right opposite Constitution Square, to descend to Monastiraki and result in electric railway Thissio and Asomaton Square. Grow with Vulcan Street, separating areas of Plaka, Psirri, and Thissio. In the middle of some, stands the Church of Panagia Kapnikarea, and within walking distance is the Cathedral of Athens and further along the bustling Monastiraki square and the homonymous metro station. One of the most cherished habits of Athens is the walk to the "lively" pedestrian street for window shopping in glitzy storefronts, watching the street performers, or for a break in a café.
