Lakshana devi temple also called Lakhna Devi temple is the oldest temple at Chaurasi Temple Bharmour. It retains many of the old architectural features of wooden temples. It is said to be constructed by Raja Maru Varman (650 AD). Other temples of Chaurasi are of later date. The temple is built on the rectangular plan. As seen from outside it looks like a modest hut having rubble and mud walls. The roof of this temple slides sideways from the central ridge and is thatched with slates. However the main gateway of the temple, square columns (Shakti Stambha) and ceiling are old.
They are carved beautifully with classical motifs and floral work. Outer door has richly carved frame on which rests a three storied pediment. Just near the entrance there is a small wooden mandapa again richly carved with figures of flying gandharvas on the capitals of pillars. It appears that the ceiling and pillars of this temple were assembled several times and their position is somewhat changed. Immediately behind the mandapa is the sanctum sanctorum again with richly carved entrance, the circumambulatory path around the sanctum sanctorum is dark the only light wherein is provided through the small rectangular windows. The astadhatu image of Lakshana devi is enshrined inside this small cella.
Durga is represented here in her aspect of four armed Mahishasuramardini, the slayer of the demon Mahishasura. The goddess is shown with a trident, sword, bell and demon’s tail in her hands, in a posture characteristic especially of early Chalukya images.
Lakshana devi idol is the only image which answers the description of Mahishasuramardini as given in Vishnudharmotra purana. Here the buffalo who charges from the left of devi is held afloat by the tail and is killed not by the trident but pressure (mardana) exereted by the right leg of Bhadrakali.
