It has always been technically and economically challenging to build constructions on a shoreline. For that reason, those constructions can be used and maintained for a long time, and today contain interesting archaeological information. Despite this, at the time of carrying out repairs, archaeologists are not usually consulted, and the history of a construction is seen as unimportant. However, with this case study of a log-barrier embankment from the early 20th-century Suomenlinna fortress, a new approach is available, challenging the way archaeologists collect data. The data collected from the site can be used together with the archaeological interpretation to aid in the plan for the reuse of the site.
