This is the mausoleum of the Sultan of Bijapur. Its circular dome is the second biggest in the world after the St. Peter Basilica in the Vatican. It is a really amazing piece of architecture. You can visit the inside and climb to the top where your voice will echo. If you are around, Bijapur is a really interesting place to visit. #bijapur #golgumbaz #karnataka #India #architecture #islamicarchitecture #dome #echo
