Tenochtitlan only had walls around the sacred precinct but of course had natural fortification by being an island in a lake that could be entered only through a few causeways. At the high end of fortification was the Tlaxcalan stronghold of Tepeticpac, up on a high hill and encircled by walls. That was their strategy of resistance against the Aztec empire. Huexotla is a site in the domain of Texcoco with a large wall and their were fortified garrisons on the frontier between the Aztec and Tarascan empires, in west Mexico. But probably more sites were not fortified than were. There was nothing comparable to the medieval European pattern or earlier fortified city states of Mesopotamia or elsewhere in Eurasia.\"§REF§(Carballo 2019: pers. comm. to E. Cioni and G.

            "description": " Amory describes fortifications and 'earthworks': 'Larger groups (sixteen to eighteen members and on up) readily developed a ‘siege mentality’, and would sometimes entrench themselves, not in caves, but in fortified earthworks or strongholds, thrown up against the inroads of their enemies. Both Óspakr and Hörðr had such fortifications built for themselves, their wives and families, and their men, Hörðr's island retreat of wood and turf being virtually impregnable. Though Óspakr's earthworks enclosed a farm with two cows, where his wife and son lived, these fortifications were not internally self-sustaining but were chiefly designed for receiving stolen goods, viz., the produce of the surrounding countryside, and for staging last-ditch defenses. It is remarkable but not unintelligible that the sizeable outlaw colony on the tiny island of Geirshólmr, under the leadership of Hörðr Grímkelsson and his foster-brother Geirr Grímsson, seems never to have engaged in animal husbandry of any sort on the island, or gone fishing in the surrounding waters, but instead preferred to launch expedition after expedition to the mainland in order to rustle from the rich coastal farms the cattle and sheep that it lacked; these would be slaughtered at once for its consumption. One may well think that cattle- and sheep-rustling was a perfectly suitable occupation for outlaws, but they were undercutting themselves by their total dependence on the mainland, and finally allowed themselves to be lured to shore by promises of freedom and were put to death in batches by a coalition of farmers who were lying in wait to dispatch them. So, at any rate, the story of the ‘Hólmverjar’ goes in Harðar saga Grímkelssonar (chs 34ff.). The colony was eradicated in three years' time without the mainland farmers' even having to assault the impregnable hall of Hörðr on one cliffside of the island.'§REF§(Amory 1992, 196) Amory, Frederic. 1992. <i>The Medieval Icelandic Outlaw: Lifestyle, Saga, and Legend</i>.

It is a theoretical possibility that some such fortifications were made exclusively of sod (this was sometimes done in house-walls) but these would still have vertical sides and seems unlikely as stone is stronger.] We have accordingly chosen to code this as 'inferred absent'."
