A CONTINUOUS STRIP WINDOW ADMITS MORE EVEN DAYLIGHT THAN DISCONTINUED WINDOWS, DUE TO FEWER CONTRASTS BETWEEN BRIGHTER AND DARKER AREAS. FURTHERMORE, LONG, LARGE HORIZONTAL WINDOWS USUALLY CAUSE LESS GLARE THAN TALL, NARROW ONES OF SAME AREA. THE FORMERS ARE QUITE WELL REPRESENTED IN SIZA’S BUILDINGS, SUCH AS AT VIANA DO CASTELO MUNICIPAL LIBRARY, WHERE LOW HORIZONTAL WINDOWS OPEN ASTONISHING VIEWS SOUTHWARDS TO LIMA RIVER, NORTHWARDS TO TOWNSCAPE AND ADDITIONAL VIEWS WESTWARDS AND TO THE CENTRAL VOID. 

AT SANTA MARIA CHURCH, A LONG WINDOW ON THE LEVEL OF THE EYE DISPLAYS SOUTH-EASTERN VISTAS TO THE SURROUNDING BUILDINGS AND VALLEY. ALTHOUGH THIS WALL RECEIVES MORNING AND EARLY AFTERNOON SUN ALL YEAR AND ALSO LATE AFTERNOON SUN DURING WINTER, THE ARCHITECT DESIGNED A DEEP WALL WITH CLERESTORIES AT THE OPPOSITE FACADE, WHICH RECEIVES LESS SUN RADIATION OVER THE YEAR. THE REASON MAY LIE ON THE FACT THAT THE LANDSCAPE AND TOWNSCAPE TO THIS ORIENTATION IS MORE INTERESTING THAN TO THE OPPOSITE ORIENTATION (BLOCKED BY AN ORDINARY BUILDING), CONFIRMING THE CAREFUL CHOICE OF FRAMED VIEWS BY SIZA. BESIDES, THE ARCHITECT, QUOTED IN FRAMPTON (2000), SAYS THIS PARTICULAR WINDOW DOES NOT INCITE RELIGIOUS CONTEMPLATION BUT INDICATES THE SOCIAL ROLE OF THE CHURCH, THAT IT IS CONNECTED TO CITY OUTSIDE.
