Biography
Biography
Building the fortress of Sveaborg became a life's work for Ehrensvärd, who kept expanding the island fortress until his death in 1772. Ehrensvärd's design was a low-profile bastion-type fortress that would follow the natural contours of the islands and thus remain inconspicuous to enemy fleets. Many of the constructions in Sveaborg are considered to be architectural masterpieces. In addition to architecture, Ehrensvärd's interests included painting, educational psychology and botany. He was also well respected by the Finnish people, who appreciated his efforts in the construction of Sveaborg, an important cultural and economic centre in the eastern part of 18th-century Sweden, which later would become modern Finland. Ehrensvärd's burial monument in Sveaborg was designed by king Gustav III of Sweden himself. Ehrensvärd was elected a member of the member of the Royal Swedish Academy of Sciences in 1739, the year it was founded. • Illustration — Augustin Ehrensvärd's tomb at the Suomenlinna fortress • Illustration — "View over Sveaborg" by Augustin Ehrensvärd
