This historic site is linked to the Challenge of Barletta because it was precisely in this medieval inn that took place the famous offensive remarks by the French -who where the conquering power- towards the Italians who at that time had not yet resolved their statehood as far as geography, but who had nonetheless a clear identity and culture. The incident resulted in a proud reaction by the 13 Italian knights and represents one of the first historical events announcing the birth of Italian nationality.

It is from the Inn of the Challenge that starts the historical reenactment of the knightly competition that has been celebrated for the last 500 years. This is also the venue for exhibitions and events, and therefore one of the most visited museums in the city of Barletta. 

Exhibitions: antique objects such as mugs, benches, tables, stools, and a fireplace with original period accessories are used to recreate the feel of the time when the historic event took place.

The entrance is marked by an ancient flag made of iron with the crest of the ancient Taverna del Sole (Tavern of the Sun), called this way because the sun used to brighten it from daybreak to sunset.
