The bus drives along the embankment of the River Daugava, providing a wonderful panoramic view of the city with its medieval church towers and the Riga Castle. Even today, the city preserves the symbols of the Soviet time – the Monument of the Latvian Riflemen and the Occupation Museum, the Academy of Sciences and the restored Cathedral of the Nativity of Christ, which used to be a planetarium under the Soviet regime. It proceeds through the historical centre of the city to the Art Nouveau district, Albert Street – a real open-air museum of architecture, where the most explicit collection of Art Nouveau buildings in Europe is located.
