Promenade deck
A promenade deck is that area of a passenger ship deck that runs outside the interior of the ship and is only separated from the outside of the ship by a railing . However, parts of promenade decks are occasionally also protected against the effects of the weather by closed outer walls, usually with large window openings. Promenade decks (see Promenade ) serve the passengers of a ship as a place to exercise in the fresh air as well as a viewing platform; for this reason they mostly lie on the upper decks of a ship.

Promenade decks emerged when the size of passenger ships increased rapidly in the last decades of the 19th century and superstructures were placed at ever greater heights on the upper deck of the hull, which until then had served as an open space for the movement of passengers . In order to replace the lost space for the passengers to move around, corresponding open spaces were left on the sides of the attached decks.
Modern cruise ships often no longer have promenade decks in the traditional sense, but instead offer space for sports activities and relaxation on their entire top deck.
