Devanahalli is a town and taluk headquarters in Bengaluru Rural district, on the northern side of Bangalore. It is best known as the home of Kempegowda International Airport and for the old Devanahalli Fort. The main postal PIN of the town is 562110.

Roads and connectivity

Bellary Road (NH 44) is the main road of Devanahalli and connects it with Yelahanka, Hebbal and the city centre. The Blue Line of Namma Metro to the airport is under construction along this highway.

Work and business hubs

The KIADB Aerospace Park, the Hardware Tech Park and the IFCI Financial City are the main employment zones around Devanahalli. Villages such as Shettigere, Sadahalli and Doddajala, between Yelahanka and the airport, have turned into residential pockets.

Homes in Devanahalli

Devanahalli has large townships, villa communities and plotted layouts, as land parcels are bigger than in the inner city. Buyers who work at the airport or in the northern business parks form much of the demand. Schools, hospitals and malls are still being added, so many residents rely on Yelahanka and Hebbal for some daily needs.
