Santo Tomé el Viejo Church was built outside the walls in the mid-12th century opposite the Gate of El Peso de la Harina (which was opened up in the 16th century when the Gate of El Obispo was closed).
Built in Caleno granite, besides some of its interior elements, it conserves the 12th-century east and south entrances, with their semi-circular arches and archivolts set on columns on the west porch and on the fascia of the capitals to the south; they boast a declaration made up of figurative, plant and geometric motifs. In 1520, the apses were removed from the upper end, together with the arches that separated the naves (replaced by columns forming two large arches on each side) and the layout was reduced to one rectangular nave.
Besides its function as a church, this Romanesque building has had many uses. After the sale of church land ordered by Mendizábal, it became a private building and was used as a garage and petrol station until 1960, when it was acquired by the State. It was designated a National Monument in 1963. It is currently an annex of the Provincial Museum and is used as a storage area for stone archaeological items; it is also open to the general public.References:
Built around AD 90 to entertain the legionaries stationed at the fort of Caerleon (Isca), the impressive amphitheatre was the Roman equivalent of today’s multiplex cinema. Wooden benches provided seating for up to 6,000 spectators, who would gather to watch bloodthirsty displays featuring gladiatorial combat and exotic wild animals.
Long after the Romans left, the amphitheatre took on a new life in Arthurian legend. Geoffrey of Monmouth, the somewhat imaginative 12th-century scholar, wrote in his History of the Kings of Britain that Arthur was crowned in Caerleon and that the ruined amphitheatre was actually the remains of King Arthur’s Round Table.
Today it is the most complete Roman amphitheatre in Britain.
