Alexandra and Konstantin were married in The Winter Palace in St Petersburg, on 11 September 1848. Konstantin received the Marble Palace in St Petersburg as a wedding gift from his parents. Strelna on the Gulf of Finland, which Konstantin inherited when aged four, was the wedded couple's country retreat. The lively Grand Duchess Alexandra Iosifovna took a particular interest in the grounds at Strelna, establishing a free school of gardening, where she taught classes herself. There were also educational toys for the children: a wooden mast and trampoline for gymnastics, and the transplanted cabin of one of Konstantin’s frigates.
