The wall is of brick, fairly high, to keep out stray animals and thieves. Most medieval gardens were defined by one or more walls which kept out intruders and sheltered the plants from sharp winds.
There is a fairly sturdy door in the wall. Sometimes these doors were strictly utilitarian; others were fanciful, especially iron or palisade gates.
The arbor or pergola over a walk and covered with vines to provide a shady walking space was one of the major features of pleasure gardens. Often grapevines were used, but others such as gourds or cucumbers, were also employed.
The location of the garden in regard to sun was and still is very important.
