Historical geography — drying mills

File with the historic drying houses. A drying plant is a polder that was created by the drainage of a lake formed by nature or by the eel or peat extraction. The most beautiful dryhouses are located south of Leeuwarden in the form of the Grutte Wergeaster Mar and the Hempensermeer. Most of the former lakes that are referred to as drying mills are dry due to improved grinding in the immediate vicinity or by tapping.本数据集文件收录历史风干棚（drying houses）相关资料。风干场是指对天然形成的湖泊，或因鳗鱼捕捞、泥炭开采形成的湖泊实施排水改造后得到的圩田。吕伐登南部的格吕特·韦加斯特马尔湖（Grutte Wergeaster Mar）与赫彭瑟梅尔湖（Hempensermeer）沿岸分布着景观最具代表性的风干棚。绝大多数曾被称作干化场的原湖泊，现已因周边区域的改良研磨作业或人工疏干而彻底干涸。
