There is another set of Sana Caves Somnath located in the newly former Gir Somnath district of the Indian state of Gujarat, at a distance of 7 km from Veraval, which was formerly in Junagadh district itself. These caves are simply called ancient Buddhist caves of Prabhas Patan, and not so much as Sana caves. Nonetheless, information about these caves has gotten mixed up in the media.
The rock cut carving includes 62 caves spread over the hill consisting stupas, chaityas, pillows and benches. The halls of few caves are dome-shaped and pillared. According to historians, the construction of caves had started by the 2nd century BC in Western India. Other historians have claimed that the architecture was constructed around the 1st century CE. A few historians have claimed that it is hard to trace the date of the caves’ architecture.
Sana Caves of Junagadh is a group of about 62 rock shelters which were carved out of soft rock. These caves were created in the period ranging between 1st century BC and 1st century AD and provided shelter to monks looking for refuge during the monsoons. Sana Caves are undoubtedly the oldest Buddhist caves in western India and boasts of rock cut pillars, stupas, benches, chaityas, viharas, a pillared hall and various domes. The shelters have been carved at various levels on and around a hillock. Some of the best archaeological symbols representing the preaching Buddhism can be seen at Sana Caves.
The largest cave, Cave 2, is named Bhima-ni-Cori and is considered to be similar to Ebhala- Mandapa, which is located at Talaja. This cave is approximately 21 meters in depth and has a width of 18.3 meters. The ceiling is 5.3 meters high and provides ample space to tourists wishing to walk through them. It also has six pillars which are located between the pilasters in front. One of the pillars depicts unique features of a concave neck between the drum and the dome.
Cave 26 and Cave 13 are different from the others. They have long verandahs with simple pillars resting on raised basements. These function as a support system for the beams above. The monasteries are also exquisitely designed with pillared verandahs which usually contain up to 4 cells at the back. The presence of benches around the hall is also an important feature of these caves.
The layout of Cave 48 is very different from the rest. It contains two halls of different dimensions. These halls contain benches around their perimeter. Most of the caves were carved at different heights and levels in the spur and could be approached by simple stairs cut into the rock. The presence of multiple tanks in this group of caves bears evidence to the importance given to water harvesting. With rock cut walls present on three sides and an oblong mouth on the other, these tanks were perfect for retaining water during the bleaker seasons. This architectural design has also been noticed in the Kanheri caves near Mumbai in Maharashtra.
These caves are distinctive in nature and are marked by their austere and simplistic designs. Most tourists notice a complete absence of engravings and ornate carvings—which are present in most of the other Buddhist caves in Gujarat. The caves also contain three chaitya grihas, which possess apsidal walls and flat ceilings. These caves are oft visited by tourists looking for deeper insights into the art forms and architectural designs of the Buddhist period. The caves are a focal point of interest for scholars, researchers and students too. A walk through Sana Caves takes you to exciting viharas, which refers to pillared verandahs containing one or two cells. These cells have rock cut benches inside them that were probably used for resting, sitting or taking shelter during the rains. Sana Caves is also known for its scenic beauty and provides a retreat to tourists wishing to enjoy the beauty and charm of the topographical landscapes beyond.
Footprints of Buddhism in Gujarat can be traced back to 270 BC. This was the period when Ashoka the Great ruled Saurashtra and was striving to spread the teachings and philosophy of Gautam Buddha across his empire. The ideology of Buddhism started gaining roots in various places in Gujarat, including Junagadh, Somnath, Velavar and the mouth of the River Indus—along with a host of other far flung areas in the state. The accounts written by Chinese scholars and travelers of the likes of Hiuen Tsiang and I-Tsing bear testimony to the spread of Buddhism in these parts of the world.
Buddhism started spreading across the nation and Gujarat in particular between the periods 27 B.C. to 470 A.D. Various archaeological remains and historical facts point to the development of embellishments and shelters in and around the areas of Somnath and Vadnagar. Sana Caves was the most prominent amongst them. These caves were located in the precincts of the Sana Hill, which is located 25 km north-east of Una and witnessed the rise and fall of a once flourishing monastery. With several water tanks and shelters to their credit, Sana Caves were constructed on the three slopes of an elevated plateau sloping down to the waters of River Rupen on the western face of the elevation.
