It is a house retracing the story of the Iranian constitutional revolution in the early 20th century. Quite well documented and well kept, although few English translations are available. The edifice is located next to the Tabriz grand bazaar, on Motahari Ave. During the years leading up to the Constitutional Revolution and afterwards, the house was used as the gathering place of the leaders, activists, and the sympathizers of the movement, among them Sattar Khan, Baqer Khan, Seqat ol-Eslam and Haji Mirza AqaFarshi. The two-story building was constructed in 1868 by Haj Vali Me'mar-e Tabrizi. It has numerous rooms and halls. The most beautiful parts of the house are a skylight and a corridor decorated with colorful glasses and mirrors. The museum is interesting only for visitors with advanced knowledge of Iran's history and the Consitutional Revolution in particular.
