They're planning on preserving the remains of Shakespeare's Curtain Theatre in place behind a glass enclosure. Its exact location had been forgotten for a few hundred years, but was found underneath a pub's back yard in 2011[0]. It is where plays like Romeo and Juliet were performed by the acting troupe which included Shakespeare himself, and so is big enough to redesign the redevelopment around and turn into a feature[1]. Its still not open to the public yet so I can't comment on whether they've done a good job or not.
