 In a study of the architecture of Chamba, instituted by the Indian National Trust for Art and Cultural Heritage (INTACH), with the objective of conserving and restoring individual heritage buildings, it has been observed that the urban architecture of Chamba evolved under three distinct phases.The first phase from 930, dating from the Rajput dynasty establishing the capital at Chamba until 1846, the second phase during the British period; and the third phase constituting the post independent period after its merger with the Indian Union in April 1948.Buildings in Chamba were traditionally constructed using local materials.
