As is well known, the theater begins with the coat rack, and Monrepo Park begins with the main gates. No reliable description of the early entrance gates of Monrepo has been preserved. Orest Somov, who visited Monrepo in 1829, was disappointed by the simplicity with which he entered the park grounds. "I dreamed that I was entering the garden through some kind of stone gorge in a high, rocky mountain, through something like the Tsarskoye Selo grand caprice; before me, heavy iron gates screeched open," he wrote about this trip. The decision to build new estate gates in the neo-Gothic style was made by the estate owner Paul Nicolai precisely during this period. In the same years, another building in the neo-Gothic style appeared in Monrepo – the Ludwigsburg Chapel. They were built in 1821 under Paul Nicolai. At that time, Russia and Europe were under the influence of neo-Gothicism. The gates were created in this same style by an unknown architect. It is possible that it was Carl Ludwig Engel – a Finnish architect of German descent. Engel worked productively for a long time in Helsingfors (Helsinki). It was he who gave the new capital of Finland its characteristic architectural appearance. After World War II, the coat of arms shield was removed from the main portal leading to the park gates, but the carved decorations and overlays were preserved. In 1954, the gates still decorated the park entrance. Judging by photographs from that time, they were in satisfactory condition. Probably, in the late 1950s, the gates were dismantled and replaced by a simple metal structure with a closing wicket. Reconstructed in the 1980s according to the project of Vyborg architect Dmitriev, the main gates generally repeat the original design, with slight differences in decoration and the absence of the family coat of arms on them. Once again, one can see at the entrance to Monrepo four pointed towers adorned with metal overlays and carved decoration.
