It’s sometimes hard to put a name to the décor on a cruise ship. For a short description on Holland America Oosterdam, subdued opulence with an old time charm comes to mind.
Hallway paintings frequently depict Dutch old world scenes, often with sailing ships.
The hallways themselves often have their own look.
Each of the stairways has its own style of artwork, which helps in getting around the ship if you recognize whether you are on the aft, mid, or forward stairway by the pictures on the walls between decks. It also helps in knowing when you’ve reached the right deck without looking for the deck number if you use that stairway often enough to know which picture is on the deck you want – like the one where your cabin is located.
Anyone who loses track of the day of the week need go no farther than the nearest elevator. All the elevators have day of the week mats which are changed daily.
Each space in the ship like bars or restaurants has décor that sets it apart from the others, yet blends with the general appearance of the ship.
Some places hold hidden surprises like the large wooden elephant hiding under the stairway in the sort of secret hallway leading to the lower level of the theater.
Even the floor has a fancy tile inlay in one hallway.
While a lot of the artwork is tasteful and nice, the ship does have some of the ugly statues that seem to be obligatory in cruise ship art since most ships have some pretty ugly statues around somewhere. The Oosterdam has headless statues in some places and some that are just heads elsewhere. A bit grisly actually those decapitated bodies and bodiless heads.
Other than the ugly statues and odd bit here and there, overall the décor of the ship is nice.

A crystal globe is the centerpiece of the Oosterdam’s atrium. Sometimes the world turns within its golden frame and sometimes it just sits still.
