Tambo   Colorado    in  Peru’s  Pisco   valley  is  one of  the best    preserved   Inca    coastal
settlements.    Built   of  adobe,  its walls   still   retain  traces  of  red,    yellow, and white
paint.  A   low ushnu,  or  ceremonial  platform,   graces  the western end of  the plaza.
Jean-Pierre Protzen.Discernible  at  many    way     stations,   administrative  centers,    and     military
settlements are the callancas   facing  the main    plaza.  There   they    served  not only
for  festivities,    but     also    as  temporary   accommodations.     Administrative  centers
were    said    to  have    included    a   palace, an  acllahuasi, and a   Temple  of  the Sun.
Without specific    historic    or  archeological   data,   it  is  difficult   to  know    whether a
cancha   is  a   palace,     a   residence,  or  an  administrative  or  religious   compound,
since   they    hardly  differ  in  design. The few positively  identified  acllahuasi, on
the other   hand,   are so  dramatically    different   from    each    other   that    they    provide
even    fewer   clues   for the identification  of  other   such    structures.
Extensive    storage     facilities  were    primarily   associated  with    administrative
centers,    although    storehouses existed at  many    other   settlement  types.  Integral    to
many     settlements     are     terraces,   both    for     agricultural    production  and     for     the
support  of  buildings,  as  well    as  waterworks  for     utilitarian     and     ceremonial
purposes.    The     construction    of  terraces    often   required    massive     movement    of
earth.  Yet,    gigantic    as  these   transformations were,   the terraces    did not destroy the
landscape   but rather  accentuated the topography. The most    elegant terraces    and
