The castle – like Dzongs with their gently tapering walls, classic lines, large courtyards and beautiful galleries, are among the finest example of Bhutanese architecture. Containing large monasteries inside, these impressive buildings, set in commanding positions on the hilltops or at the confluence of the rivers, are also the administrative centers of the regions. Overlooking the main buildings, small castle like fortresses called Ta – Dzongs (literally meaning watch towers) were built for defense. But the most common architectural sight in Bhutan are not these majestic buildings but chortens or stupas, which are small shrines built originally to house sacred relics.
