2015 Southeast Asian Games were held at the new National Stadium. Numerous matches also took place at various venues across Kallang. On 9 August 2016, the new National Stadium hosted the 2016 NDP – the first NDP in the new National Stadium, and the first NDP held in Kallang after a decade of hiatus.

Landmarks Kallang is home to numerous "historic sites" of Singapore, as officially designated by the National Heritage Board (NHB). These include the Central Sikh Temple along Towner Road, the former Kallang Gasworks along Kallang Road, the Merdeka Bridge along Nicoll Highway, the Balestier Plain along Balestier Road, the old Kallang Airport along Stadium Link, the historic Farrer Park (now called "Farrer Park Field") along Rutland Road, as well as the Jalan Besar Stadium along Tyrwhitt Road.
