Born in 1794, the 57-year-old was from Nelson, Lancashire, and the oldest of 11 children, before beginning work as an apprentice weaver.
He then switched his profession to becoming a pupil at a lock carpenter on the Leeds and Liverpool Canal in 1811.
This change of career proved successful, as Mackenzie went on to make his fortune by working on canal and railway projects in France, Spain and Belgium.
After he passed away, his estate worth £42 million in today’s money was left to his youngest brother Edward.
It was Edward himself that had the pyramid made and paid for in memory of late brother, 17 years later.
Visitors to the churchyard today can still see the 170-year-old tomb but is gated off to preserve the structure.
