Zamek Radzikowskich w Radzikach Dużych

Radziki Duże, Polan, Poland

---

Zamek Radzikowskich w Radzikach Dużych, located in north-central Poland's Kuyavian-Pomeranian Voivodeship near Rypin, is a Gothic defensive residence built in the late 14th century (around 1380-1394) by Andrzej Ogończyk, a Dobrzyń castellan and Teutonic ally, or possibly after 1413 by his descendant Jakusz who adopted the Radzikowski name.

The small fortress, a family seat for the Ogończyks-turned-Radzikowskis, was rebuilt around 1510 by Mikołaj Radzikowski with Renaissance details like ornate window frames before passing through heiresses to the Plecki and later families amid Teutonic raids and Swedish destruction in the 17th century.

By the 19th century, it lay in ruins with surviving wall fragments, cellars, and northern Renaissance influences, now an atmospheric archaeological site in a rural setting.
