I live locally but have only seen it once it's worth seeing if you find maps/ history interesting I thought it was expensive for what I was but you do get to see the chained library as well.

Must see in Hereford. there is nothing like it elsewhere. The chained library is also well worth a visit.

It is difficult to make an incredibly out-of-date map interesting, expecially when it won't get you from A to B by the shortest possible route, and may actually get you utterly lost, so Hereford has done its best with a rather unprepossessing artifact.

Worth a visit but quite expensive, only suitable for children if they are interested & old enough to do the quiz & brass rubbings.

Really interesting and informative., well presented and along with the old library, though provoking. Really liked this.
