The architectural and archaeological surveyon Ile de la Passenot only documents archaeological remains and architectural features, but also both complements and adds to the partial and sometimes misleading records which can be found in the archives. The work will permit the implementation of appropriate approaches to Cultural Heritage issues, including preservation and conservation, on this evocative islet. Ways in which the cultural assets can be enhanced and presented to future generations of Mauritians and totourists can only be explored once a proper understanding of what survives has been assessed.

     Current research design is largely focused on establishing the sequence and dates of the complex alterations to the defenses and other military illustrations from the French period to the early 19th century. Closely linked to the unraveling of this sequence is the gaining of greater insights into the precise ways in which installations, such as different types of gun emplacement, actually functioned. We might then bebetter able to address the extent to which new designs reflect technological advances in ordnance. Finally, the research will help us to place more precisely the coastal defenses of Mauritius within the wider pattern of European colonial endeavors.
     Yet another aim is to record the many graffiti, the majority of which were carved in the 19th century by British officers and troops.

     The sequence of defenses dating to the French Period is seen to be more complex and multi-faceted than had been expected. Cleaning part of the Upper Battery revealed stone gun mountings with iron fittings (for which no parallels have yet been found) while work on the Central Platform uncovered unexpected features within it that require further exploration.
     Clearance and recording around the base of the 19th century Observation Tower was completed in advance of the National Heritage Trust program of restoration. Part of the Upper Battery parapet walling was restored and experimentation was conducted with a selection of appropriate materials.
     Systematic recording of the graffiti by means of digital photography was begun.
