We’ve looked up this house a handful of times, and couldn’t find anything concrete. But a few weeks ago, we walked past and noticed something… concrete. Literally.

Etched in a patch of sidewalk out front — and spared from any subsequent paving is this: “John D. Shea, 1899.” That’s all we’ve got, but it’s more than we had before we looked down.

This massive house has six bedrooms, five bathrooms and more than 4,000 square feet. Which detail is your favorite?
