CALLE MORETO, 4
" Los Jerónimos ", as it was
popularly known , was one of
Madrid ' s most important convents .
Beside it was the Cuarto Real ,
subsequently enlarged to become
the Palacio del Buen Retiro in the
time of Philip IV .
Of the convent , only the church ,
behind the Prado Museum , and a
cloister remain today . The latter
deteriorated badly during the
nineteenth century and , following
an agreement with the
ecclesiastical authorities , it was
restored and became part of the
Prado Museum in the extension
designed by architect Rafael
Moneo . Because of its external
appearance the cloister is known
popularly as the " Moneo Cube ".
