Apex (Latin for top, peak, summit) may refer to:

A museum is an institution that cares for a collection of artifacts and other objects of scientific, artistic, cultural, or historical importance and makes them available for public viewing through exhibits that may be permanent or temporary. Most large museums are located in major cities throughout the world and more local ones exist in smaller cities, towns and even the countryside. The continuing acceleration in the digitization of information, combined with the increasing capacity of digital information storage, is causing the traditional model of museums (i.e. as static “collections of collections” of three-dimensional specimens and artifacts) to expand to include virtual exhibits and high-resolution images of their collections for perusal, study, and exploration from any place with Internet connectivity.

The English "museum" comes from the Latin word, and is pluralized as "museums" (or rarely, "musea"). It is originally from the Greek Μουσεῖον (Mouseion), which denotes a place or temple dedicated to the Muses (the patron divinities in Greek mythology of the arts), and hence a building set apart for study and the arts, especially the Musaeum (institute) for philosophy and research at Alexandria by Ptolemy I Soter about 280 BCE. The first museum/library is considered to be the one of Plato in Athens. However, Pausanias gives another place called "Museum", namely a small hill in Classical Athens opposite the Akropolis. The hill was called Mouseion after Mousaious, a man who used to sing on the hill and died there of old age and was subsequently buried there as well.
