Many, many yeas ago we went to Cascais in Portugal and visited a very large fair set amidst pine trees. There were food, drink and many other stalls.
We cannot remember the site nor date we visited, though it was probably late in the year. Can anyone help with details if this fair is still ongoing? Thanks.
Can you remember anything else about the festival? Was there a particular theme? If it was near the waterfront it could have been the Festival of the Sea.
Otherwise it's possible that it was simply an outdoor market. Cascais is known for its good markets and shopping.
