Amjad Ali Shah's eldest son, Wajid Ali shah, who was eventually destined to be the last ruler of Avadh, ascended the throne of Avadh in 1847. Wajid Ali Shah was a great patron of singers, musicians, dancers and artists. He was also greatly interested in architecture. He started building the Qaiser Bagh Palace Complex as soon as he came to the throne. This vast complex was built between 1848 and 1850 at the cost of 80 Lakh rupees including furniture and decoration. The inner courtyard of Qaiserbagh with it’s lawns was called jilokhana. In the center was a Baradari flanked by two Mermaids gates (Lakkhi Gate) at eastern and western ends. On the right end was chandi wali baradari, which was paved with silver and the khas muqam and Badshah Manzil, which used to be the special residence of the king. On the left was a large group of buildings termed as chaulakkhi kothi built by Azi Mulla Khan, which was later sold to the king. Nawab Khas Mahal and other honoured ladies of the royal Harem lived there. During the mutiny days begum Hazrat Mahal held court from this Kothi. The buildings at the Quaiserbagh Quadraangle were occupied chiefly by ladies of the harem. To the left of the western Lakkhi Gate was the Roshan-ud daula kothi, built by Nasser-ud-Deen- Haider Wazir later confisicated by wazid ali shah and renamed as Quaiserpasand. One of his favourite wives Nawab Mashuq Mahal used to live in it. Of the large oblong enclosure of elegant and imposing two storied house one wing of which was pulled down after the war of 1857, the other still remains. It was in this atmosphere of gaiety and merriment, that the british annexed Avadh on Feb. 11 1856, deposing Wazid Ali Shah.
