Still continuing along the western periphery of Montereau we explore in greater detail the boundary where the old city meets the cramped suburbs. There are no stunning historical landmarks here, however there are a couple of quaint local sites that only the saviest and most knowledgeable tourist would recognize. The open subway station is the most notable, and is one of the few surviving relics of the original Montereau metro that was constructed decades ago. While all other stations throughout the city have been renovated and retrofitted to fit a more modern styling and function, the Métro de Trottier has been preserved in it original architecture. Such is the job of the Authority on Aesthetics, an arm of the Society for Historical Preservation of the government. Its job is to not only save and maintain the many historic buildings throughout Genevra, but also to influence current construction as to maintain the visual harmony of the nation.
