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:
German crusaders known as the Livonian Brothers of the Sword began construction of the Cēsis castle (Wenden) near the hill fort in 1209. When the castle was enlarged and fortified, it served as the residence for the Order's Master from 1237 till 1561, with periodic interruptions. Its ruins are some of the most majestic castle ruins in the Baltic states. Once the most important castle of the Livonian Order, it was the official residence for the masters of the order.
In 1577, during the Livonian War, the garrison destroyed the castle to prevent it from falling into the control of Ivan the Terrible, who was decisively defeated in the Battle of Wenden (1578).
In 1598 it was incorporated into the Polish-Lithuanian Commonwealth and Wenden Voivodship was created here. In 1620 Wenden was conquered by Sweden. It was rebuilt afterwards, but was destroyed again in 1703 during the Great Northern War by the Russian army and left in a ruined state. Already from the end of the 16th century, the premises of the Order's castle were adjusted to the requirements of the Cēsis Castle estate. When in 1777 the Cēsis Castle estate was obtained by Count Carl Sievers, he had his new residence house built on the site of the eastern block of the castle, joining its end wall with the fortification tower.
Since 1949, the Cēsis History Museum has been located in this New Castle of the Cēsis Castle estate. The front yard of the New Castle is enclosed by a granary and a stable-coach house, which now houses the Exhibition Hall of the Museum. Beside the granary there is the oldest brewery in Latvia, Cēsu alus darītava, which was built in 1878 during the later Count Sievers' time, but its origins date back to the period of the Livonian Order. Further on, the Cēsis Castle park is situated, which was laid out in 1812. The park has the romantic characteristic of that time, with its winding footpaths, exotic plants, and the waters of the pond reflecting the castle's ruins. Nowadays also one of the towers is open for tourists.
