Even the smallest and oldest of the houses on Anna Maria Island feature certain design and architectural elements that are not only functional, but beautiful. It’s easy to take them for granted (and some people might even take them for granite), but the gray and white marble sills that form the bottom of so many island windows are just such a solid, visually pleasing detail.
It makes a lot of sense to put marble at the base of an island window … especially those of the traditional jalousie design, which are often left open even when showers come through. The angled panes of the opened jalousie window catch and deflect most of the rain away from the sill. But if some of the rain gets through, a marble sill is preferable to wood. The water won’t penetrate, and can be easily wiped away. Damp wood leads to many problems in the Florida climate, including rot, mildew and even termites.
