Jagati is situated at a distance of 16 Km. from Boudh . Near the village at Gandhradi, is situated the famous twin temples of Nilamadhava and Sidheswar. These temples were constructed under the patronage of the Bhanja rulers of Khinjali mandala in 9th century A.D. These two temples were built on one platform which are exactly similar to each other. The one on the left hand is dedicated to Siva named Siddheswar and its sikhara is surmounted by a Sivalinga.The second is dedicated to Vishnu ,named Nilamadhava and its sikhara is surmounted by a wheel of blue chlorite. The principle of construction of the Jagamohanas at gandharadi is slightlt different than that of other temples. Their roofs are built on the cantilever principle and originally it appears to have been supported on twelve large pillars arranged as a hollow square .
Thus each side had four pillars of which the central ones flanked an opening. Originally these two Jagamohanas appear to have been open on all sides but later on the lintels on all sides appear to have given away and then it became necessary to fill in the gaps between pillars with the exception of the four openings with ashlar masonry. At the same time the side openings were filled up with a jali or lattice of blue chlorite towards the bottom and a frieze of four miniature temple sikharas over it. This arrangement is not followed in later temples where the ingress of light into jagamohana is through four or five stone pillars in the opening used as window bars.
The style of ornamentation in the jagamohans of the Gandharadi temples is altogether different. Even stylized chaitya-windows are rarely to be seen at Gandharadi except at the bases of the pilasters of the vimana . the ornamentation on these two jagamohans is very simple and much less overcrowded . The importance of the Gandharadi temples lies in the fact that they provide a link and that a very important one, in the chain of the evolution ,in the chain of the evolution of the mediaeval Orissan temple type.
The Gandharadi temple is also locally known as Chari Sambhu Mandira ( the temple of four Sambhus or Siva lingas). In the Siva temple Siddheswar is the presiding deity. In the Jagamohan ,to the left of the door leading to the sanctum is the siva Linga called Jogeswar and to the right of the door is the linga called Kapileswar. At a little distance from Siddheswar standsa the temples of Paschima Somanath ( Siva), the door of the temple opening to the west.
Some images of considerably antiquity are found worshipped in shrines nearby. Notable among them are the images of Ganesh in the temple of Paschima somanath and a beautiful image of eight armed Durga worshipped under a banyan tree,the later image being badly eroded due to the vagaries of weather. These images probably once adorned the siddheswar temple .Portions of beautifully carved door steps in black chlorite and other decorative motifs have been unearthed. In the vicinity of the temple. A five feet (1.52 meters) high Hanuman image of good workmanship is being worshipped near the village Jagati and a beautiful carved Nabagraha slab is lying in the cornfield. Archeological Survey of India has preserved this place. .
