Emoticon represents the Kaaba, the central sanctuary of Islam in Mecca. Destination of the great pilgrimage (Hajj) for every Muslim.
The kaaba emoji was introduced in 2015 and released as part of the Unicode 11.0 standard. This emoji can be found under the
travel and places category. Because the kaaba emoji has been around for quite some time, it should display correctly in the majority of operating systems.
