ShanaiKahr was a settlement on the planet Vulcan and was located fifteen kilometers away from ShiKahr. The city was home to the ShanaiKahr General Academy and was home to the Terran embassy. (TOS novel: Mindshadow)

Before the events of the Vulcan Reformation, ShanaiKahr was led by a powerful and vicious Kolinahru mind lord called Zakal. (TOS novel: The Lost Years) Tu'Pari and Kovar had relatives at ShanaiKahr in the time before the events of the Sundering. (TOS - Vulcan's Soul novel: Exodus)

Sometime between the 2260s and the 2280s, Valeris travelled to ShanaiKahr to apply for Vulcan citizenship. She met Saavik there, who told her of Spock's plan to sponsor a Vulcan to Starfleet Academy. (TOS novelization: Star Trek VI: The Undiscovered Country)

The novel Mindshadow states that ShanaiKahr is the planetary capital which contradicts other sources such as LUG.
