In this article the religious and ethnocultural phenomenon among the Gagauz known as «hajjilyk» – pilgrimage to Jerusalem for the worship of the Holy Sepulcher – is studied. This tradition, which is one of the oldest forms of worship among the Christians, has been preserved within the Gagauz and Bulgarians for many centuries without any change. It was considered the greatest of all kinds of pilgrimage and was therefore perceived as a spiritual feat. The second most important place of worship, according to the national and religious tradition, was Holy Mount Athos. Such a unique religious and ethnocultural phenomenon as the hajjilyk, which served the function of spiritual renewal and development of the people, is an intangible cultural and religious heritage.
