Inscription

Black mineworkers were involved in gold mining in Johannesburg from 1886, but were excluded from the white minerÕs union for many years. It was only in December 1982 that the National Union Mineworkers was formed. In 1995 this site became the NUM headquarters. The building was constructed in 1934 for Hubert Davies and Company which imported, manufactured and installed engineering equipment and machinery for industry and the mines throughout Southern Africa. Founded in 1894 by J. Hubert Davies, a consulting engineer from Scotland who had come to the Rand in 1889, the companyÕs first big project was the electrification of various mines.

A culmination of research gathered over many years, the Online Johannesburg Heritage Register is being launched on Nelson Mandela Day 18 July 2025.

Among the many heritage sites featured is Chancellor House, the downtown offices of Mandela and Tambo Attorneys in the 1950s. After having been vacant and shuttered for more than a decade, this iconic building is being revived and brought to life once again as offices for the Community Development Department, which oversees the City’s Arts, Culture & Heritage Services.
