Colégio Santiago Internacional students from years 7, 8 and 9 visited the Torre de Tavira which is an old water tower next to Igreja de Santa Maria and the castle and is home to the Camara Obscura which with a clever use of a rotating mirror and magnifying glasses projects a 360 "tour" of Tavira onto a large horizontal screen.

On a clear day like the one our students enjoyed last week, the "camera" can see up to 30 miles away.
