The Chapel of St. Nicholas the Wonderworker on Milk Mountain is a small Orthodox church built in the 1840s according to the classical style project of provincial architect P. I. Fursov on the site of the former Bread Rows in Kostroma.

Originally, the chapel had the shape of a rotunda, but it was later slightly altered, losing its round appearance. The entrance and facade of the chapel are adorned with columns, yet its architecture is quite simple overall. During the Soviet era, the chapel was closed and repurposed as a commercial space, during which its dome was dismantled. In 1977 and 1979, the building underwent restoration. During the perestroika period, the chapel was used as a store called 'Instruments.' In 1995, the chapel was handed over to the diocese and became a dependency of the Trinity-Sypanov Pakhomiev-Nerekhta Monastery. Currently, the chapel has been fully restored: a cross has been installed, the domes have been gilded, and the interiors have been updated.
