Twenty three kings and queens and a large number of royal children are buried in this pantheon. It is one of the earliest examples of Romanesque art, as is illustrated by the short, thick columns crowned by capitals and decorated with plant motifs reminiscent of Asturian art. Others are beautifully historiated in tribute to Visigothic tradition. The wonderfully preserved 12C frescoes feature an outstanding collection of New Testament themes and scenes from rural life. Note the calendar of seasonal tasks inside an arch.
