Адмиралтейские верфи
The peak of the trade relations between Vriezenveen and the Russian capital was between the years 1850 and 1870. Some Vriezenveners made an exceptional career in Russia. Jan Hoek and Jan Gerritsen Servijs became purveyors to the Russian royal court and Wicher Berkhoff rose from carpenter's son to director of the Admiralty Shipyard in Saint Petersburg.
