An archaeological survey was completed during the summer of 1975.

The cemetery was the subject of an archaeological survey in the late 1990s.

An archaeological survey has found that the church is much older than previously thought.

Since it was private property, no archaeological surveys were made.

The archaeological survey of the site shows that it had no buildings.

From late 1997 until early 1998, a thorough archaeological survey of the site was conducted.

An extensive archaeological survey was conducted at the site in June 2009.

At the same time a new archaeological survey was conducted using modern equipment and techniques.
