Bangsal Merah Boepati, a tribute to the East Java history from mid-18th century to the end of 20th century, is based on the lives of the regents of East Java, successors of Kyai Brondong through several generations. Research reveals that the two regents who once ruled Surabaya together got into a war against each other. As a result one of the regents' sisters ran away and seeked for shelter in a ship that belonged to a man of the Ching Dinasty, who arrived in Java in 1754. They then married and began the Tjoa Dinasty in Indonesia. As years passed, later successors of regents of Surabaya also formed friendships with several Straits Chinese figures of Java, such as The Toan Eng, Tjoa Sien Hie, etc. Some of the artworks related to these late regents, discovered by Tugu Hotels, demonstrate a fusion between traditional Javanese culture and Straits Chinese influence.
The Bangsal Merah Boepati can be used to house smaller conferences, lunches, dinners, and other events up to 20 guests.
