One of the oldest surviving chimneys is in a castle in Kent, England. Dating from the 12th century, the fireplace it vents is just a recess in the thick masonry wall. The chimney is a short incline in the wall with a hole to the outside. After the 12th century, fireplaces and chimneys were constantly being refined. By the 15th century, masons were building decorative chimneys that were an important element of Tudor architecture. Today, chimneys are again becoming showpieces, especially on large custom homes. A sampling of the distinctive chimneys architects are designing and masons are constructing is provided. Photographs of a dozen unique chimneys are shown.
