In this special issue of MUSE SG, we celebrate the 30th anniversary of NHB. It features an opinion piece by Professor Tommy Koh, who ruminates on what heritage means to him. We also trace some of NHB's milestones and achievements including the Singapore Heritage Festival, now into its 20th edition, as well as the recent opening of the Children's Museum Singapore. In addition, the issue features research driven and supported by NHB, such as that on Shanghai plaster, a stone-like finish that gives 14 of our national monuments their stately facades, as well as histories unearthed of our foods, neighbourhoods and wayside shrines. We also take an in-depth look at our National Collection and how NHB cares for the 250,000 works it comprises.
