More than half of Reja de Don Gome Street is occupied by the rear facade of Viana Palace, whose main door is reached by surrounding the building. Originally dating from the 14th century, its current appearance is the result of a series of subsequent renovations. It is a civil construction from the medieval-modern period. It was declared a National Historic-Artistic Monument in 1981. The incomparable setting of its twelve courtyards and an imposing garden allows gardeners to enjoy the most varied selection of flowers.
