We saw a number of beautiful buildings, including the Geological and Geophysical Institute of Hungary, pictured above. In fact, we had a chance to go inside the Institute building and admire its architecture. Later we also visited the Four Seasons hotel, which is located in the art nouveau Gresham Palace.
