Svetitskhoveli Cathedral (11th century) and Jvari Monastery (6th century) in Mtskheta are amongst the most significant monuments of Georgian Christian architecture, and are historically significant in the development of medieval architecture throughout the Caucasus. Of special significance are early inscriptions, which form a valuable reference in the study of the origins of the early Georgian alphabet.
In the outskirts of Mtskheta are the ruins of Armaztsikhe fortress (3rd century BC), the Armaztsikhe acropolis (dating to the late 1st century BC), remains of a "Pompey's bridge" (according to legends built by Roman legionnaires of Pompey the Great in the 1st century BC), the fragmentary remains of a royal palace (1st–3rd century AD), a nearby tomb of the 1st century AD, a small church of the 4th century, the Samtavro Monastery (11th century), and the fortress of Bebris Tsikhe (14th century). The Institute of Archaeology, and the garden of Mikheil Mamulashvili are also worthy of note. There is also a monument to sculptor Elena Machabell.
