Zandvliet is a Belgian town forming part of the Antwerp district of Berendrecht-Zandvliet-Lillo. The place dates back to 1135 when it was known as Santflit, meaning "a navigable passage through sand".In 1622 the Spaniard Ambrogio Spinola constructed a fortification with seven bastions around Zandvliet, to strengthen the defenses of Antwerp against the northern Netherlands.
