The Metro Plaza building is located in the heart of Tallinn, just a few steps from the historical origin of the major routes linking Tallinn with the rest of the world. It is between the mediaeval Old Town and the rapidly developing modern city centre. The fact that the building lies on the boundary between different eras is reflected in the appearance of the building. The first storeys of the Metro Plaza rest on the century-old walls of the Rotermann Department Store. The upper stories of the building are set back an increment from the old walls and present a presentable, calm exterior. Because the old walls were preserved, the side of the building facing Viru väljak and Mere puiestee is transformed into an arcade street for pedestrians with an Old Town-like ambience, especially at night when illuminated.
