Hereford Cathedral; Mappa Mundi
Hereford Cathedral has a couple of local saints (one martyred in Saxon times; the other generally holy in medieval times), a construction of tough red sandstone, and, among other more traditional memorials, a shrine to the SAS, whose “home” town is the city. (the SAS even get their own modern stained-glass window.) I suppose the SAS monument is in the long tradition of military church memorials, especially those of armoured medieval knights whose effigies rest in repose. The Cathedral is surrounded by beautiful gardens.
