Leave the modern world behind and step into a night bursting with 16th-century spectacle at COSI After Dark: Knights at the Museum on March 12. In partnership with the Ohio Renaissance Festival, COSI transforms into a living, breathing celebration of chivalry, charm, and playful chaos. The Queen’s Court, jesters, rogues, nobles, and rowdy pirates will roam the museum, greeting guests with the same larger-than-life spirit that fills their legendary village. Expect booming laughter, dramatic banter, and immersive character moments everywhere you turn as costumed performers bring the magic of the faire indoors, from swordplay flair to mischievous antics to moments of pure Renaissance pageantry.


Explore hands-on science activities woven throughout the building, then wander a lively marketplace featuring authentic festival artisans offering handcrafted goods and treasures worthy of any noble, peasant, or adventurer. Raise a themed cocktail, gather your companions, and prepare for a night where 400 years of fun collide with the power of science, right inside COSI’s walls.
