The Henry and Johanna Van Maren House-Diamond Filling Station is a historic building located in Pella, Iowa, United States. The Van Marens had this two-story brick building constructed for their family home in 1877. Both were first generation immigrants from the Netherlands. Henry was a wagon and carriage-maker. They bought the property their home stands on under Johanna's name, and it remained in her name until she died in 1912 and it passed to Henry.
