Ducové (Hungarian: Ducó) is a municipality (village) situated in western Slovakia, near the spa town of Piešťany.

[6][7] Ducové is known for an archaeological site on the Kostolec hill, where a Great Moravian fortified settlement has been unearthed.

The Slavic court was founded in the mid-9th century after the fall of the nearby hill fort in Pobedim, frequently associated with the unification of principality of Moravia and Nitra.

[8] It was protected by a massive oak palisade, doubled on one side and built on top of the prehistoric mound.

[9] Interior space was divided by additional palisades and occupied by residential buildings, outbuildings, a Christian rotunda church and a graveyard.
