The Oosterpoort (Eastern Gate) - Hoorn
The Oosterpoort dates back to 1578 and in 1601 the small house for the gatekeeper was placed on top. The gate is a paragon of power and awe. At the time the gate was built, the city was only accessible through four gates. The rest was walled up. One of the four gates was the Oosterpoort, the only remaining gate and therefore one of the most prominent monuments in Hoorn.
The heavier the weapons became, the less the gates could withstand them. Earthen ramparts with stone parts could better withstand these heavier weapons. This changed the function of the gates and walls. The Oosterpoort is a good example: it was not built to defend, but mainly to control who wanted to enter and leave Hoorn. In addition, the gate was used to collect tolls and excise.
