The gateways of the Sanchi Stupa are called Toranas. These are four intricately carved gateways (North, South, East, and West) dating to the 1st century BCE during the Satavahana period. They depict scenes from Buddha's life and Jataka tales through beautiful carvings. 'Cariots' is likely a typo for 'chariots', 'Frescoes' are wall paintings, and 'Gopuram' refers to South Indian temple gateways.
