The fortress grew into a palace known as Tre Kronor 'Three Crowns'.During the late 16th century much work was done to transform it into a Renaissance style Palace under King John III. iN 1690 It was rebuilt in Baroque style after the designs of Nicodemus Tessin the Younger in 1690. Work began in 1692 and finished in 16997, but that same year most of the palace was destroyed by fire. Again it was rebuilt by Nicodemus, and work carried out over the years which were finally completed in 1830.
