Arches appeared in architecture as early as the 2nd millennium BC although it was the Ancient Romans who brought these structures into the architectural vernacular we know today.  This was ever so obvious in Paris where everywhere one turns, be it a corridor, an entry passage, a train station or a theater, the arch was present.  The beauty of the arch form is often ignored until we realize it’s presence is ubiquitous.  The arch also speaks volumes of history.  Even in a modern setting, the arch’s reference to classicism is both subliminal and obvious.  Look at arches – you will appreciate them!
