"Brook was a small estate. At the time of the Domesday (1086) it consisted of about 350 acres. There were 7 acres of meadow, a church, mill and a small wood. In the Medieval period it was owned by the great Cathedral Church of Christ Church in Canterbury. ..... The farmyard beside the road includes a barn of 1370 which stands to the east of the yard. The Court Lodge of 1430 and later buildings occupy a roughly rectangular site beside the road.” (extract from the description in Traditional Kent Buildings, Volume 5 by Margaret Spark MA)
I have visited the museum three times, in March 2009, August 2011 and September 2015. It consists of the large Medieval, aisled barn facing the former farmyard, a nineteenth century oast house and other outbuildings which now house craft workshops and displays. It is owned and administered by Wye Rural Museum Trust. They have a website and are also visible on social media including Facebook.
