A gas turbine engine includes a shaft compartment containing at least one main shaft which rotates about a main axis of rotation; and a tower shaft engaged with the at least one main shaft for rotation about a tower shaft axis of rotation, the tower shaft being mounted in a bearing compartment extending away from the shaft compartment, wherein the bearing compartment is sealed against leakage from inside the bearing compartment to ambient. The seal can be produced using a tower shaft seal held in a seal housing and sealing against one or more faces of the tower shaft assembly or components.
