From its first occupation (Bronze Age 2500-100 BC): Ceramics and funerary equipment, loom weights, punches or needles, among others.

From the Roman Period (Flavian Dynasty 1st century AD): Vessels and pottery for packaging and for domestic use such as plates, pot, bowls, plates, glasses, etc.

From the Medieval Period, a distinction is made between the Arab civilization (Almohad invasion) and the Christian one: Decorative elements and domestic life such as remains of tiling, lamps, jugs, plates, etc.

From the Modern Era, passage doors, keys, chest, safe, portraits, etc. are collected. Three very significant pieces stand out from this period, the first is the painting by Juan de Bolaños, El viejo (the only preserved example of this author's pictorial work) that represents the scene of the Battle of Las Navas de Tolosa that occurred near the castle by Castro Ferral. The second is the impressive jar that is displayed in the hall of the Baeza Museum for storing oil. And finally, the door known as the three keys, which once housed the most important documents of the city in the High Town Hall building.

These are therefore pieces that serve as an excellent way for visitors to learn about the life of man and touches on the history of the city. But the main capital of the Baeza Museum is its own public, who when visiting it recovers the collective memory.
