The Sancto Antonio (better known as St. Antonius Mill) is a grain mill in Halsteren. The Antonius mill was built in 1817 and exists 200 years! The initiative for the construction of this mound mill was taken by Jan Goossens. He was a miller in Oud Gastel and saw that there was a market for a mill between Halsteren and Bergen op Zoom. The mill was ready on June 13, 1817, the saint's day of Saint Antonius.
On the closing stone above the entrance of the mill stands:
'Sancto Antonio XIII JUNII MDCCCXVII'
The mill and mill shop at Halsterseweg 57 are open every Wednesday afternoon and Sunday afternoon from 13:00 to 17:00. The mill can then be viewed. In the mill shop there are various baking mixes that make the mill of its artisan ground flour.
