6. Municipal Building
Don’t worry about conspicuously lingering about in this government building; there is no need to go inside to find Guastavino tiles. The south wing of the Municipal building on Chambers Street is fitted with a vaulted tile ceiling, though not in the characteristic herringbone pattern.
The Manhattan Municipal Building was the first to incorporate a subway station in its base, and it’s regarded as one of the most beautiful stations in the city, featuring 11 columns. According to MCNY, Guastavino “devised a series of elegant vaults to cover the space, adapting to its various shapes three basic forms: the barrel vault, used along the length of the colonnades; lunettes, curving between the columns; and groin vaults, to accommodate the diversely shaped polygons spanning the internal columns.” Also, check out 12 other secrets of the Manhattan Municipal building, including how you can access the cupola on the top.
