The most prominent landmark in Thimphu is the Tashichho Dzong (meaning: "Fortress of the Glorious Religion") located on the west bank of the Wang Chuu. The imposing white washed structure, as seen now, has undergone several renovations over the centuries following fires and earthquakes. Subsequent to introduction of the Drukpa Kargyu lineage by Lama Phajo and Zhabdrung acquiring the Dzong in 1641, the Dzong was renamed as Tashichhoe Dzong. During this time the practice of using a Dzong both as a religious centre for lamas and administrative centre for civic administration was introduced. Apart from the throne room and offices of the King of Bhutan, as an administrative building, it houses the Central Secretariat, the offices of the ministries of Home Affairs and Finance. The National Assembly, which used to be located in the Dzong is now in a separate building called the SAARC building.
