portugese architect joao luís carrilho da graca  recently received the piranesi prix
de rome 2010 international prize for his project the musealization of the archaeological
site of praça nova of são jorge castle, in lisbon, portugal.

the hill occupied by são jorge castle is the site of the first known human settlement
of lisbon, a vantage point overlooking the tagus estuary and its inland territory. the
excavation of the castle’s praça nova, begun in 1996, uncovered remnants of its
successive periods of inhabitation, leaving the exposed archeological site open to an
intervention of protection and musealization, addressing the themes of revelation and
readability of the palimpsest that an excavation represents with a pragmatical approach
aimed at clarifying the palindromic quality of interpretation of the site. the first action
was its clear delimitation with a precise incision: a wall of corten steel to contain
the higher perimetrical surface.

the same precision was used in the inserted steps, landings and seating, setting them
apart from the excavated walls. a hovering structure protects the existing mosaics of
a XV century palace, its underside covered in a black mirror that allows the reflection
of the pavements. the canopy for the protection of the xi century muslim domestic
structures and its frescoes was an opportunity to reproduce its spacial experience.
conjectural, abstract and scenographic, the white walls float above the visible
foundations, touching the ground on mere 6 points, while its covering filters the sunlight.

underlying the whole site, the evidence of the iron age settlement is exposed and protected
through a volume that invites the curiosity for the observation of its interior, leading the visitor
around the excavated pit to the point where both the physical and time distance of the exhibited
structures is made obvious. the palimpsest of the site history is thus decoded and the possibility
of its palindromic time-space reading made clear through the experience construed by its
material protection and musealization.
