Surabaya is Indonesia's second-largest city and the capital of the province of East Java. It is situated on the northeastern shore of Java Island along the edge of the Madura Strait. Known as the 'City of Heroes,' Surabaya gained this title due to its significant role in the Indonesian National Revolution against Dutch colonialism. The city's name is believed to derive from the Javanese words 'suro,' meaning shark, and 'boyo,' meaning crocodile, which are also part of local mythology. Surabaya boasts a vibrant economy and is known as a center of business, commerce, industry, and education in eastern Indonesia. The Port of Tanjung Perak is one of the busiest in the country, underlining Surabaya's importance as a trading hub. The city’s architecture mirrors its colonial past with a mix of influences, including Dutch colonial buildings, Chinese shop houses, and modern skyscrapers. Key attractions include the Submarine Monument, a retired Russian sub, the Heroes Monument, and the Surabaya Zoo. Surabaya is also famous for its local cuisine, such as 'Rujak Cingur' and 'Sate Klopo.' The city serves as a gateway to Mount Bromo and the island of Madura.
