Location of polder het Grootslag in the ambacht Drechterland, West-Friesland, The Netherlands. Darkest grey: Het Grootslag in 1423, at its inception; Wervershoof joined in 1460. In 1926, the former Houterpolder (light gray area) was joined with het Grootslag. The division in 'bannen', the contours of the land and the extent of polder het Grootslag were taken from a map of 1775, "Nieuwe Kaart van het Dykgraafschap van Dregterland", [1], and various textual sources, notably G. de Vries, Azn., Zeeweringen en Waterschappen van Noord-Holland, Joh. Enschedé en Zn., Haarlem, 1864, pp. 402--405, and the 1936 edition by D. Kooiman, [2], Alphen aan den Rijn: N. Samson, 1936, p. 644.
