Chhota Imambara Though Popularly called as the Chhota Imambara, the Hussainabad Imambara stands to the west of Bara Imambara. Built by Nawab Mohammad Ali Shah (1837-42), it is more ornate in design with exquisite chandeliers, gilt-edged mirrors, silver mimbar and colourful stuccos which adorn the interiors. A golden dome and fine calligraphy on the exterior of the building makes it a truly exceptional monument of Mughal architecture (open : 0600 hrs to 1700 hrs.).

The Lucknow School of Architecture was an experiment by the resurgent Nawabs of Awadh. It was an attempt to preserve the Mughal school of architecture by experimenting with different materials and innovating new concepts.

Among the extant architecture there are religious buildings such as Imambaras, mosques and other Islamic shrines, and secular structures like enclosed gardens, baradaris, palace complexes.

The following are distinct features of Lucknow architecture :

• Use of English Baroque style of architecture at Dilkusha Kothi.
• Use of Fish as a decorative motif especially on Gates
• The use of Chattar (umbrella) as in the Chattar Manzil
• The fusion of European and Indian style as the La Martiniere Lucknow
• The Baradari ( the twelve doorway pavilions)
• Rumi Darwaza
• Enclosed Baghs like Sikandar Bagh
• Vaulted halls such as the Asafi Imambara
• The labyrinth at Bara Imambara
• Taikhanas

The Bara Imambara, Chhota Imambara and Rumi Darwaza are testament to the city's Nawabi mixture of Mughlai and Turkish style of Architecture. And La Martiniere Lucknow on the other hand, is a testament to the Indo-European style of architecture. Even the new buildings are fashioned with the characteristic domes and pillars, and monuments lit at night form a main attraction of the city. The city's main market of Hazratganj is a fusion of the old and modern.
