Among the best known features of Bang Rak District are the skyscrapers of Si Lom and Sathon, some of which—Mahanakhon, State Tower, and Jewelry Trade Center—are among the tallest buildings in the country. The Bangkok Bank Headquarters, built in 1981, is iconic for its pioneering application of modernist design to a concrete high-rise building, as was the original Dusit Thani Hotel building, which was demolished in 2019. They stand in contrast to colonial-era historic buildings such as the Neilson Hays Library and the British Club on Surawong Road, and the Sathon Mansion near Sathon–Naradhiwas Intersection. Other historic buildings are concentrated in the waterfront Charoen Krung area, including the nineteenth-century Portuguese and French embassies, Customs House, East Asiatic Building, and original Author's Wing of the Mandarin Oriental Hotel. (Other luxury hotels on the river include the Shangri-La and the Royal Orchid Sheraton, while many others line Sathon, Si Lom and Surawong roads.) Dating later, from 1940, the General Post Office building on Charoen Krung Road now houses the Thailand Creative & Design Center, a sponsor of the Creative District project. From the same period, the Bangkokian Museum and Bang Rak District Local Museum, on a side street of Charoen Krung near Maha Set Road, showcases a middle-class family home of the time and features exhibits about the district's history.
