The museum at Valdemāra Street 47 was opened in 1969 in the building of the maritime school that was opened in 1864 at the suggestion of Krišjānis Valdemārs.  The school trained more than 1,000 sea captains and helmsmen.  The exhibition at the museum relates to the operations of the school, as well as the building of sailing ships on the Vidzeme shoreline during the latter half of the 19th century and the early part of the 20th century.  There is a collection of anchors, as well as the top of the Ainaži lighthouse, which was once washed away by the sea, but has been restored.
