not sure it qualifies as a megalith, but these woods very near my house, where i saw the deer yesterday morning...
i only went in them properly for the first time a couple of years ago, cos they are basically inaccessible unless you climb walls or fences.
i was idly googling them today and it turns out they are in fact quite special...
a roman kiln / tilery was discovered there in the 1950s
There's this great description of it in a book from the 1600s:
"In the yeare of owre Lord 1590 certain Colyers working in xxxxxx in xxxxxxx in framynge a pitt to burn charcoales discoverid a certain worke in the earthe of most fyne bricke, yt resemblid a Roundwell a four yeards depe or not so much, cunynglye walled with bricke and having upon the topp a very broad brickstone coveringe the same with a round ledg wrought upon it whereon where written divers Roman carecterrs namelye these-COHIIIIBRE. Next adjoining to yt had been an archid cave wherin great fyers had bene made, and there were four condithes going from the place in the lower part of the grounde and comyng forth some 8 or 9 yeards of it, wherein had runyd some kind of metall for the stones was all congealed together. There was about it both redd, and blewe, and yellow bricke verye curyous and good, a kind of hard sinders in many places
with some traces of very thin earthin pots verye curyously wrought It was placed in the myddst of the wodd in a descending place near unto a spring of water. The name of the wodd is callid xxxxxxx, but the old name is Springer’
There's a lot of pottery from it is in a local museum - here's a few of the pieces
also, they contain one of the UKs oldest Yew trees.
"The girth of this tree is not known. Its height is not known. This tree germinated / was planted around the year 1600 ± 200, which makes it around 421 ± 200 years old"
Both of these are quite rare for the area.
