Hi, I'm sure that if you keep an eye on the following websites there will be some further details

There was quite a bit going on in 2007, 199th annivesary, so I'm sure there'll be even more this coming year: try using "batalha" "Vimeiro" "Roliça"

I think it's a sure bet that there will be something going on during the third / fourth weeks of August

Best wishes
