Markham Building, Victorian commercial building in Central Business District, Johannesburg, South Africa.

The Markham Building is a six-story Victorian commercial structure located at the corner of Eloff and Pritchard streets featuring a clock tower with four faces imported from Scotland. The building displays Second Empire architectural details including metal panel roofing and round porthole-style windows throughout its facade.

Henry William Markham, who came from England to Cape Town in 1873 and built a men's outfitting business, opened a Johannesburg branch in 1895. The building was erected between 1896 and 1897 to the design of Cape Town architect George Ransome, who had already designed the Markham's store in Cape Town. Completed in 1897, it was then the tallest building in the city and stood out so plainly that it was nicknamed "Markham's Folly". It was saved from demolition in 1978.

The building housed a prestigious gentlemen's outfitter that served wealthy businessmen in early Johannesburg. It represented the arrival of refined shopping culture during the city's rapid growth in the 1890s.

The building occupies a corner lot at the intersection of Eloff and Pritchard streets, facing the Cuthberts Building across the same crossing. The clock tower rises above the six storeys, so the corner is easy to pick out from street level.

The clock tower held an artist's studio, and the clock itself was imported from Scotland with four faces. The building's nickname, "Markham's Folly", came from how plainly it stood out in the centre of Johannesburg.
