place air vent at top or bottom of door

Hi - I have a sort of lean to shed that is built onto the back of my victorian terraced house, with a sloping corrugated metal roof (which is sound)- it's triangular, 2 walls are the stone boundary walls (100+ years old) and the third is the exterior kitchen wall (ditto age). A corner of this triangle is cut off and is filled by the solid wood door to the very small garden.
In winter damp seeps through the stone walls - in summer the tin roof superheats the air inside and the interior drips with condensation - there is no ventilation. I can't ventilate through the boundary walls or into the kitchen, so the only options are the roof and door. keeping the door open means that when it rains (which it does at some point on nearly 3/4 of days of the year) the interior gets soaked.
It's a useful space for the kids plastic outdoor playthings, but I can't keep anything that is wooden/fabric or metal in there as it all rusts/moulds/disintegrates.
Before admitting defeat and pulling the whole thing down I want to try and fit air vent/s to the door to create some air flow- where would it be best to site these? top of the door/bottom/both? or would one in the door and something in the roof work better?
many thanks!

Door should be fine but would be ideal if there is an air flow to it.
A top and bottom vent would be my preference. This would give an air flow and would be "good building practice". The air flow is a detail I have on my airing cupboards. A 225x225 MAP vent (white plastic, also in aluminium, IIRR) is cheap at B&Q etc.and easy to fit. Even better would be one with an open and close flyscreen detail - still very cheap. Then if it is pouring down you might shut the vent if it prevents rain getting in.0 -
fab thanks - hadn't thought of an open/close vent - I'll have a look :AA/give up smoking (done)0
