Saint-Petersburg is a beautiful city in Russia that has grown significantly in population from 1.2 million in 1897 to over 5 million today. In the late 19th century, the city had wooden and stone bridges, magnificent palaces and buildings, and people traveled by horse as there were no cars yet. It has since modernized with the addition of a metro system and other infrastructure changes, but remains one of Russia's most historic and culturally significant cities.
