The Botik of Peter the Great (also called St. Nicholas) was a miniaturized scaled-down warship discovered by Peter the Great at the Royal Izmaylovo Estate in 1688. It was restored by Karshten Brandt, and Peter learned to sail using the boat on waters near Moscow. It was stored in the Kremlin of Moscow by Peter and later enshrined in St. Petersburg. Peter continued to use it in state ceremonies and ordered that the boat be sailed down the Neva River on 30 August of every year. It was used in state ceremonies of later Russian monarchs, including the wedding of Catherine the Great and Peter III of Russia, as well as the centennial celebration of St. Petersburg. Catherine built a boathouse in the 1760s to store it.
