Soltaniyeh is the brilliant capital of the Mongol kings at the beginning of the l4th century, 135 km. from Qazvin. Of its splendid past Soltaniyeh has preserved only a tradition of fine copper and steel-working and the large Mausoleum of Soltan Oljaitu Khodabandeh. This imposing tomb was originally intended as the burial place of the first Shiite imams and was completed in 1307. It dominates the entire surrounding plateau and testifies to the amazing skill of the Mongol architects of the period. It subsequently served as a model for mausoleums throughout the country.
