Just okay.
8 € entrance, 3 levels, mixed exhibition of basics of history of Bari, basics of St. Nicolaus history and then some religious artefacts. Very nice staff. There is a nice cafe right on the corner.
I don’t think I would recommend it very deeply unless you are passionate about Nicolaus, there are many better museums in the region for example Museo Sigismondo Castromediano in Lecce (what a gem!).
