This month’s desktop calendar (sorry, a couple of day’s late!) is an image of the castle at Obidos, in Portugal. This is an old medieval town near the centre of Portugal and it’s a place that we like to visit each time we are back in the mother country. The local authorities have tried their best to maintain the original ‘old world’ feel to the place, which is good on the one hand but does turn it into a bit of a tourist trap on the other. Nevertheless, it remains an interesting place to visit, the highlight of which for me and my daughter are the walk along the top of the battlements that surround the town, from which this photograph was taken.
