“Casa Guidi,” as Robert and Elizabeth Barrett Browning affectionately called their apartment in the fifteenth-century Palazzo Guidi, was their home for nearly all of their married life, from 9 May 1848 until Elizabeth's death on 29 June 1861. They took the apartment furnished for three months in the summer of 1847 and found life there so pleasant that when in the following year it became available, they established themselves in Casa Guidi on a permanent basis and furnished the apartment themselves. Their only child, Pen, was born in Casa Guidi. Elizabeth wrote Casa Guidi Windows and Aurora Leigh there and Robert, many of the poems in Men and Women. It was to Casa Guidi that Robert brought home “the square old yellow Book” which, metamorphosed by him, became The Ring and the Book. These were years of great happiness for the poets, and it is appropriate that Casa Guidi should be preserved as their memorial.
