Imperial Russian celebratory street and architectural decorations have always impressed me by their extravagance and their ingenuity. Below are photographs of such decorations in the city of Saint Petersburg.
The façade of Gostiny Dvor, Nevsky Prospekt, decorated for the Coronation of Nikolas II, 1896.
Bicentennial Celebration of the City of Saint Petersburg held at Peter I's Square, 1903.I will post more photographs for Saint Petersburg and will start a similar thread for Moscow.
