We derive the static three-dimensional spherically symmetric solution of the Einstein equations in an empty five-dimensional universe, and analyse the effective four-dimensional perspective. The radius of the compact fifth dimension is regarded as a local quantity. Our main conclusion is that the extra dimension becomes visible, and the associated Kaluza-Klein gauge interaction singular, when approaching the modified Schwarzschild horizon. The possibility of "massless" black holes is noted.
