About Mayo College
Figure 1: Front view of main building
Mayo College (informally Mayo) is a boys-only independent boarding school in Ajmer, Rajasthan, India. It was founded in 1875 by Richard Bourke, 6th Earl of Mayo, who was the Viceroy of India from 1869 to 1872. This makes it one of the oldest public boarding schools in India. It aimed to provide the leaders of the princely states with an education similar to that given by Eton College. The British built Mayo for the sons of the Indian upper classes, particularly the princes and nobles of India. The Main Building was completed in 1885 and was designed by Major Mant while the construction of the Boarding Houses by the States began independently.
About Alwar House Alwar House, is a significant structure standing within the campus of prestigious Mayo College of Ajmer. Constructed in 1876, it was designed by Mr. Joscelyn as a residence and is a rectangular structure with a courtyard in between. The building is of Rajputana architectural style with the presence of various architectural features like bangaldar roof, chhatris, octagonal turrets along all the four edges of the building. With time, various additions and alterations have been done in

the building. New rooms have been added on the first floor and large spacious rooms on the ground floor were subdivided due to increased requirements felt by the residents over the time. The changes done over the time matches the architectural style and the materials used in the building. In the past few years, it was being used as the staff residence and further additions and alterations were carried out in the building i.e., addition of new toilet blocks on both the floors, addition of temporary slabs and almirahs in the rooms, raising the ground floor level with respect to overall site level, thus causing a drastic decrease in room heights etc. These interventions have led to various problems like water seepage and rising dampness causing the structural instability. Presently the Building is in under execution of conservation process. Alwar house will be restored to be re-used as the new media centre for the school.
Architectural Description Alwar House is a hybrid structure built in Rajputana and British style of architecture comprising features of both the styles. The building also reflects the local influences of Alwar principality in its architectural vocabulary. A series of residential quarters are arranged symmetrically around a rectangular court in the double storeyed building. The building is of great architectural and historic significance.
1. Arched Verandahs The projected balconies on the first floor of the building have arched openings which give a perfect composition of flat and decorative surfaces on each facade.

2. Bangaldhar Chhatri Bangaldhar chhatris in local stone, a typical feature in Rajputana architecture, are seen on the exterior façade of first floor of all the blocks.
Figure 4: Bangladhar Chhatri
3. Stone jaalis The entire structure has 33 – 34 types of jaalis with a wide range of designs. The jaalis are in red sandstone and of varying sizes. At few places jaalis are deteriorated due to regular moisture ingression.
