When City Hall opened in 1812, some New Yorkers feared it was too far north; after all, the city at the time was centered at the southern tip of Manhattan.
But the city quickly marched northward and this French-inspired Federal structure (the two designers who built it won $350 for their efforts) has been in use continually for more than 200 years.
Surrounded by stately city buildings and offices and often the site of riots and demonstrations, it maintains a simple elegance.
