[citation needed] By the end of the 14th century, the saltworks passed to the family of Dmitry Shemyaka, providing him with income required to wage prolonged wars for control of Moscow.

It was in 1450 that both Galich and Soligalich were finally seized by Vasily II of the Grand Duchy of Moscow.

Towards the end of the 17th century, half a dozen churches were rebuilt in brick, surviving to the present day.

Seven decades later, separate Kostroma Governorate was formed, with Soligalich as one of the uyezd centers.

Painter Grigory Ostrovsky was active in Soligalich; the only paintings known to be by his hand are currently held in the town's regional museum.
