What was the primary function of Westminster Abbey since its first coronation in 1066?

The primary function of Westminster Abbey since its first coronation in 1066 has been serving as a location for royal coronations. This historic church has been the venue for the crowning of English and later British monarchs, beginning with William the Conqueror. This tradition not only helps solidify the legitimacy of the monarch but also marks a significant ceremonial event tied deeply to the nation's history and identity. The Abbey has hosted every coronation since then, creating a rich tapestry of royal tradition and pageantry that reflects the enduring nature of this institution within British culture.

While other functions, such as housing national memorials or hosting significant events, have also taken place at Westminster Abbey, the central and defining role of the Abbey has been the coronation of monarchs, which is a ceremony that embodies the history and continuity of the monarchy in the UK.
