The landmark=yes tag indicates that feature is a landmark.

For instance, landuse=cemetery + landmark=yes.

Features are tagged as landmarks to highlight that they stand out from the surrounding landscape, although not necessarily from a great distance. Remember than there is usually a way to tag something to describe it without suggesting it as a landmark.

Old proposed values

exclamation mark

This feature has been labeled as deprecated. The recommended replacement is: usual tag and landmark=yes.
The reason is documented in Deprecated features. You are still free to continue to use or interpret this tag as you see fit since OpenStreetMap does not have “banned features”.
Under no circumstances should you (semi-)automatically change “deprecated” tags to something else in the database on a large scale without conforming to the automated edits code of conduct. Any such change will be reverted.

It was proposed to tag every nautical landmark with seamark=landmark + landmark=*

The S57-catalog differs between a bunch of useful landmarks we should use in landmark=* at least:

Many of these have its own dedicated INT 1 symbol for rendering on nautical maps
