by treaties. Aspects of its architecture are consistent with the Iliad's description of mythic Troy, and several of its sublayers (VIh and VIIa) show potential signs of violent destruction. Thus, these sublayers are among the candidates for a potential historical setting of those myths. Troy VI and VII were given separate labels by early excavators, but current research has shown that the first several sublayers of Troy VII were in fact continuations of the earlier city. Although some scholars have proposed revising the nomenclature to reflect this consensus, the original terms are typically used to avoid confusion. Troy VI Troy VI existed from around 1750 BC to 1300 BC. Its citadel was divided into a series of rising terraces, of which only the outermost is reasonably well-preserved. On this terrace, archaeologists have found the remains of freestanding multistory houses where Trojan elites would have lived. These houses lacked ground-floor windows, and their stone exterior walls mirrored the architecture of the citadel fortifications. However, they otherwise display an eclectic mix of architectural styles, some following the classic megaron design, others even having irregular floorplans. Some of these houses show potential Aegean influence, one in particular resembling the megaron at Midea in the Argolid. Archaeologists believe there may have been a royal palace on the highest terrace, but most Bronze Age remains from the top of the hill were cleared away by classical era building projects. The citadel was enclosed by a massive wall whose limestone base is visible to modern day visitors. These walls were periodically renovated, expanding from an initial width of to around 1400 BC. During the Bronze Age they would have been overlaid with wood and mudbrick superstructures, reaching a height over . The walls were built in a "sawtooth" style made up of - segments which joined at shallow angles. This characteristic is common in the walls of Mycenaean citadels, though at Troy it is also found in other buildings, suggesting that it may have been decorative. The walls also have a notable slope, similar to those at other sites including Hattusa. However, the walls differ from contemporary Aegean and Anatolian sites both in their lack of figural sculpture and in their masonry. While Troy VI's walls were made entirely of close-fitting ashlars, contemporary sites typically used ashlars around a rubble core. Troy VI's walls were overlooked by several rectangular watchtowers, which would also have provided a
