LOCATION
CULTURAL AND HERITAGE VALUE:
Terracotta brick vernacular architecture of Bengal and Manipur, bear testimony to the varied and ancient traditions of terracotta that
have flourished in India over five millennia. Eastern India has experienced a vast array of the art of Terracotta in forms of temples &
ornamentations that have withstood the test of time. With the vagaries of nature and decay over ages, these temples are in need of
immediate preservation and maintenance.
Stone was rare in these areas.
Being composed of small units, use of bricks gave higher
flexibility and greater constructional possibility in these
seismic prone regions.

THE DAMGED TEMPLE
WHY THE CONSERVATION WAS NEEDED ?
•The conservation revitalized a decaying landmark of terracotta craftsmanship and
terracotta brick architecture.
•It was a protective step towards the cultural resource of Manipur and its History.
•It promoted the Socio-religious values.
•The adaptive reconstruction / conservation helped to spread the traditional art of terracotta
not only amongst the workers involved with the project but also amongst the general mass.
VEGETAL GROWTH
Excessive rainfall caused vegetation growth
which led to cracks and dislodged the
masonry.
Damage due to salt petere and
dampness in masonry structure.
THREE SUCCESIVE
EARTHQUAKES
•Collapsing of main ceiling and partial collapsing of
sidewall.
•Settlement problem in foundation part.
•Action of soluble salts like chlorides, sulphides,
nitrates etc .

MAIN DAMAGES FACED BY THE STRUCTURE
1. THE ROOF COLLAPSED AFTER THREE SUCCESSIVE EARTHQUAKES EXPOSING
THE STRUCTURE TO FURTHER WEATHERING HAZARD.
INNER VIEW

vaulted ceiling collapsed.

vaulted ceiling before it collapsed.
(Taken from old records at site)
Inspired from the weaving pattern of
traditional bamboo basket, the entire
form of the vault was reconstructed with
a grid of bamboo.
Pic: The side wall had
fallen partially owing to the
damaged caused by
neglect as well as
earthquake.
Bamboo grid and
sparingly used steel have
been camouflaged by
a layer of lime Surkhi.
Original roof was 40” thick throughout till
the top. The new roof starts from 15” at
the base and 6” at the top, reducing
the load by 200 mt.

THE CONSERVATION PROCESS
4. CRACKS AND CREVICES DEVELOPED DUE TO
EARTHQUAKE
WAS
FURTHER
WEAKENED
BY
VEGETATION GROWTH.
The glass “tell-tale” signs were put up over the existing cracks to study the
threat of further deterioration and were found broken after 6 months.
Vegetal growth was
cleared
from
the
superstructure and the
walls were restored.
Vegetation growth on the
walls and around the super
structure
Cracks which were found
going
up
to
the
foundation, that part of
the structure was carefully
dismantled,
the
foundation reset and the
super structure remade.

THE CONSERVATION PROCESS
• 10’ wide trench was dug up
around the temple.
• A continuous band of corbelled
masonry buttresses have been
provided
to
strengthen
the
foundation against the lateral
seismic force.
• An additional plinth protection
band of stone was provided
around the structure at the ground
level.
16 types of bricks were found to be used in the
construction of Shri Govindji Temple
Old bricks were dug out from the
debris of the monument, sorted
out and aired and dried in the sun.
Brick bats were kept separately for
crushing and making into Surkhi
(brick dust).
