The house in Huizum (near Leeuwarden) where Klaas Plantinga's grandfather (Klaas Jans Plantinga) and his wife (Binke Hessels) used to live. The street is called "Dorp" (English "village"). The house is on the right, to the front. A picture postcard from 1905. This village is near Leeuwarden and used to be a thriving center of planting/gardening/horticultural activity. The name "Plantinga" is derived from this occupation.
The house in modern times, after having been refurbished in the 1970s. The original Plantinga house is here seen split into two seperate residences. This picture was taken in 2010. These days, Huizum is no separate village, rather a neighbourhood of Leeuwarden. The street is now called "Huizum Dorp".
The house where Klaas Pieter Plantinga lived with his mother and stepfather, at the Noordvliet in Leeuwarden. Their house is the sixth house from the left, behind the ship's mast. Klaas' stepfather was called Popke van der Sluis van den Bosch and he was a book printer and paper salesman who worked from this house. It no longer exists, having long ago been replaced by newer houses.
The house at Secretaris Haitsmalaan 1 in March 2012. The bust in the front is not of Klaas Plantinga, rather of Titus Brandsma (born 1881 near Bolsward, educator and resistance fighter, died in Dachau in 1942).
