In the Padmanabhaswamy temple of Thiruvananthapuram, a group of six vaults were discovered during an excavation for the temple. When the first five vaults were opened, insurmountable treasures were unearthed. From crowns to sacs of jewels to statues and thrones, the value of the contents was estimated to be billions and billions of dollars. Vault B, however, has since remained unopened. This vault, in particular, is decorated by twin cobras, a symbol of impending danger, in Indian mythology. Because of superstition, the doors remain closed. These doors remain one of the greatest current mysteries in Indian archeological history. 

Another wonder relating to Indian temples is the Kailash Temple. Ordered to be built by Rashtrakuta King Krishna I, it is considered to be an extraordinary architectural feat. The temple itself was built between 756 and 773 AD, and was carved entirely from one stone, featuring elaborate patterns, stories, and carvings along its walls. Kailash Temple is located within the Ajanta / Ellora Caves, which also features other sets of temples and monasteries.
