Saint Isaac's Cathedral

Saint Isaac's Cathedral is the largest, most beautiful church and the fourth largest Christian cathedral in the world. It took over four decades to build. Additionally, the upper balcony offers the highest viewpoint in Saint Petersburg (since there are no tall buildings there). This cathedral was constructed in the mid-19th century as the main church of the city. It is said that Saint Isaac's Cathedral is the most elaborately decorated cathedral of its era, made with gold leaf weighing a total of 100 kilograms and decorated with over 43 types of marble and other stones. Due to its grandeur, it once hosted the wedding ceremony of Peter the Great and Catherine in 1712. The most distinctive feature is its golden dome, which is the largest symbol of the city. This is likely true as the magnificent golden dome can be seen from many places in the city.
