In the dense forest of the Novgorod region, half a kilometer from the village of Maly Borok, lies the enchanting estate of Zavetnoe. This place was known back in the time of Catherine II when it was a small hamlet.

Over time, the estate expanded, owners changed, until in 1914 it was acquired by the nobleman, architect, and inventor Mikhail Antonovich Tokarsky. According to his designs, the existing buildings were reconstructed, and new significant structures appeared on the vacant lots: two two-story houses with wings, a chapel-tomb, entrance gates, a greenhouse, a summer theater, and a fountain. Thin-walled reinforced concrete was used for their artistic creation.

Even now, when the complex is almost lost, special attention is drawn to the romantic miniature chapel on an artificial hill, made in the style of a medieval castle. Tokarsky saw a similar castle in France and recreated it in his estate in a smaller version.

The chapel consists of a round and a square tower with pointed windows, and above the entrance once stood the family coat of arms. Inside the chapel were rich interiors, and the ceiling featured a large insert of blue glass, which also served as the floor of the observation deck. The top of the building is adorned with a tent with a cross and a crescent, and a spiral staircase leads to the tower.

The entrance to the estate was decorated with a reinforced concrete arch with a two-story tower, designed with battlements and an open gallery.

After the revolution, Tokarsky voluntarily handed over the estate to the Soviet authorities and financially assisted the peasants of the neighboring village. The main house was dismantled after 1945.

Tokarsky himself passed away in the winter of 1941-1942 while on the way to Kirov during the evacuation from Leningrad.
