BIR meaning in Airport Code ?

Biratnagar (Nepali: विराटनगर) is a metropolitan city in Nepal, which serves as the capital of Province No. 1. With a population of 242,548 as per the 2011 census, it is the largest city in the province and also the headquarters of Morang district. Biratnagar is located 399 km (248 mi) east of the capital, Kathmandu, and 6 km (3.7 mi) north of the bordering town of Jogbani in the Indian state of Bihar. The highest peak in the world, Mount Everest, is situated 174 km (108 mi) north of the city.

Biratnagar was declared a metropolitan city on 22 May 2017, thus pushing the total population to over 240,000. This made it the fourth-most populated city in the country following the urban agglomeration of Kathmandu and Lalitpur, Pokhara, and Bharatpur.

The city is home to the Biratnagar Jute Mills, the first large-scale industry of Nepal. Besides being considered as the industrial capital of Nepal, the city has contributed actively to the Nepalese democracy movement by being the birthplace of five prime ministers of democratic Nepal. The latter claim is also evident from the fact that the first labor strike leading to the anti-Rana movement started from Biratnagar.

Modern-day Biratnagar serves as an entry point to eastern Nepal as well as north-eastern India. It is the second Nepalese city, after Janakpur, to have a connection with the Indian Railways and the only city other than Birgunj to operate an integrated check post (ICP) on the Indian border.
