David Gareja, also known as Davit Gareji or Tavadis Gareja, is a rock-hewn Georgian Orthodox monastery complex located on the border between Georgia and Azerbaijan. The complex is situated on the slopes of Mount Gareja and extends into both countries. It is one of the important cultural and religious sites in Georgia.

The David Gareja complex was founded in the 6th century by David (St. David Garejeli), one of the Thirteen Assyrian Fathers who arrived in the region to spread Christianity. The complex includes numerous monasteries, churches, and cave cells carved into the rock. The architecture of the complex is unique and reflects a blend of Georgian, Armenian, and Persian influences.

The monastery has faced various challenges throughout its history, including invasions, occupations, and neglect. Currently, the border between Georgia and Azerbaijan passes through the complex, leading to occasional disputes between the two countries.

David Gareja is recognised for its historical, cultural, and religious significance and is an important pilgrimage site for Orthodox Christians. The site has also attracted tourists interested in its architectural and historical aspects.
