In addition to the air watch tower, there are even more beautiful things to admire. There is a boulder that has been in the IJsselmeer for years.
At a meeting of the Oudemirdum Recreation Foundation it was discussed that the thick boulder in the sea near the Hege Gerzen actually had to be removed, because children regularly injured themselves on the stone in the summer. The stone was in the swimming area.
Before the stone was brought to the surface, an inspection was carried out, which revealed that the stone was located approximately 150 meters from the coast. There was approximately 1.10 meters of water at the site. The top of the stone was approximately 25 cm. below the water surface. There was an indentation of 3 cm at the top of the stone. The notch was probed with a prod, the stick disappeared by 40 to 50 cm. in the stone. There appeared to be a break in it.
After recovery, the stone was weighed. The base weighed 4,760 kg. and the top part turned out to be 4,480 kg. to weigh. So a total of 9,240 kg. The stone was then placed on the pedestal.
