Gronowo is a village in the administrative district of Gmina Lubicz, within Toruà  County, Kuyavian-Pomeranian Voivodeship, in north-central Poland.
The village was founded in 1412. Beginning in 1437 the village was owned by the Teutonic Order, and helped support the garrison in Toruà Â. In the Second Peace of Thorn (1466) ownership passed to the Polish king as crownlands. The king mortgaged the property and from 1520 to 1570 Gronowo was briefly owned by the city council of Toruà Â. In 1570 it again became a royal holding and in 1639 King Wà Âadysà Âaw IV enfeeoffed the land, and it then passed through the hands of various noble families. In 1798 the owner was Samuel Wolff of Gronowa. The current Wolffów Palace was built about 1910 replacing an earlier one. In 1920 the Wolff estates were acquired by Prince Wà Âadysà Âaw (Vladimir Puzyna).
