Excavation carried out prior to the development of Park Lane Hospital, Musselburgh revealed the partial remains of a probable ring-groove house of first millennium B.C. date and a later sub-rectangular, post-built structure attached to a curving fence line. Although initially interpreted as a Roman granary, it now seems likely that the features were the partial remains of a timber amphitheatre associated with Roman Inveresk. Ditches and a number of negative features of unknown date and function were also recorded.
