What is a porthole?

A porthole is composed of a small circular hole, which acts as an opening on a surface and filled with a glass plate supported by a frame. It is used when it is necessary to be able to observe the outside, exposing oneself as little as possible. This detail differentiates it from normal windows.

Where does the term porthole come from?

The Italian word oblò derives from the French word " hublot ". This French word probably derives in turn from the Franconian word " huve ", which in Italian means cap or cap.
