IISc campus harbors both exotic and indigenous plant species with about 110 species of woody plants. The roads on the campus are named after the dominant avenue tree species. The architecture of the main building, which today houses the administration and the Faculty Hall, is classical in style, fronted by a grey, handsome tower. In front of it stands the work of Gilbert Bayes, a monument erected in the memory of J. N. Tata. At its feet is an inscription that serves to remind future generations of the generosity of Jamsetji Tata and the persistence with which he worked for the welfare of India. The building, as one of the prominent landmarks of Bangalore, was designed by C. F. Stevens and Company of Bombay in 1912–13. The buildings for the metallurgy and aerospace departments were designed by the German architect Otto Königsberger in 1940. Challakere Campus A second campus is in Challakere, on lot of land. Infrastructure developed here includes the Talent Development Centre, Skill Development Centre funded by HAL under CSR Act, Solar Power Research Center and a Climate Observatory. The Centre for Sustainable Technologies has commenced its activities here under the project "C-BELT" i.e., the Centre for Bio-energy and Low-Carbon Technologies. Janardhana Swamy, then Member of Parliament from the Chitradurga Lok Sabha as well as a notable alumnus of IISc and Amalan Biswas, then DC of Chitradurga District played significant roles in setting up the IISc's new campus at Challakere. They were instrumental in identifying all the required 1500 acres of land for the new campus, getting the existing building leased from the Sheep Farm, obtaining the various needed approvals from the government, and having the initial funds released from the State.
