While little photographic evidence exists about the Warren at Marrickville, these are two lovely engravings that show how lovely this building was.
Thomas Holt's home appears as a backdrop to children's games and fun in this plate from March 1870. Jump rope and a lively game of cricket can be seen as some of the past times enjoyed by the children of the Victorian era.
By 1886 the Warren Estate had been purchased by the Carmalite Nuns as a convent. At this time a more somber scene was engraved of the nuns heading to prayer.
Both images, and some other lovely old pictures of Marrickville can be found on the Dictionary of Sydney's webpage.
