StarCraft II: Wings of Liberty/Protoss buildings

Fleet Beacon
Allows the carrier and the mothership to be built.

Gateway
Has the ability to be upgraded into a Warp Gate, which can "warp in" units across the map to any spot within the range of Pylons or deployed Phase Prisms. Each Warp Gate can only "warp in" one unit at a time and is subject to a cooldown period before it can use the ability again. In addition, newly warped in units will gradually materialize and be vulnerable for a period (like a newly warped in Protoss structure), and if the Pylon or Phase Prism is destroyed while the unit is being warped in, the unfinished unit will be lost.

Nexus
Builds Probes and Motherships.

Dark Shrine
It allows Dark Templar to be built.

Photon Cannon
All purpose base defense that detects stealth.
