Sarphatimonument in Amsterdam

You're standing at the Sarphati Monument, in the middle of Sarphatipark in the De Pijp neighbourhood. Look at the round stone structure on the little hill. It looks like a small temple, and it's twelve metres tall. That hill isn't natural, by the way: it was built specially for the monument. The whole thing went up in 1886, designed by Jacobus Roeland de Kruijff.
