Can Ferrerons in Premia de Mar, near Barcelona, boasts an impressive Roman edifice featuring an expansive octagonal central hall measuring 14.8 meters in width - equivalent to roughly 50 feet as measured by Romans themselves. With no central pillar to obstruct the space, the walls stand tall at over 3 meters high and have withstood the test of time thanks to their clever construction using lime and stone mortar. What's more remarkable is that these robust walls are a whopping 55 cm thick, providing unwavering support for the structure. Archaeological analysis has conclusively shown that only a sturdy turf roof could provide adequate coverage for this magnificent space, leading experts to propose a detailed model of roofing that would do justice to this ancient wonder.
