The magnitude of some projects indicates that this was the result of combined efforts from multiple palatial centers . Most notable of them are the drainage system of the <unk> basin in Boeotia , the building of a large dam outside Tiryns , and the drainage of the swamp in the Nemea valley . Moreover , the construction of harbors , capable of accommodating large Bronze Age era vessels , such as the one found at Uluburun , like in the case of the harbor of Pylos , is also noticeable . The Mycenaean economy also featured large @-@ scale manufacturing as testified by the extent of workshop complexes that have been discovered , the largest known to date being the recent ceramic and hydraulic installations found in Euonymeia , next to Athens , that produced tableware , textiles , sails , and ropes for export and shipbuilding .
