So here they are, some of the beautiful windmills depicted on stamps from Portugal (Hi, Paulo!).

The 20c shows a mountain windmill, which is a typical example of windmills from the Bussaco Hills in the Penacova region.

The 50c is a Beira Litoral Province windmill from the Figueira da Foz (Brenhas) area.

The 2e is an Azores windmill from the island of St Miguel.

While scanning these, I suddenly remembered that lovely set of American stamps with windmills, so I'll continue this windy theme tomorrow (very much in keeping with the weather here!)
