The Gosha Gala Tower is actually an arch portal which serves the main entrance gate to Baku's Old City. It blends perfectly with the overall environment, and it's a significant crossroad of routes through the city. It's the beginning of the Old City, the end of Fountains Square and it hosts a big Tourist Information Center, where visitors can get every kind of necessary information they might need. There is also a little set of stores, placed right inside the gates where you can find some gifts and thematic souvenirs.
