The Temple of Hephaestus is a well-preserved ancient Greek temple built in 450 BC, dedicated to the God Hephaestus, the protector of blacksmiths, craftsmen, artisans, sculptors, metals, metallurgy, fire and volcanoes. This may be one of the most well-preserved temples, not only in Greece, but in all of Europe.

It was built on a site of a Jesus college. It was a foundation, set up by clerics from Madrid's Royal Monastery (Monasterio de la Visitación), under the patronage of the princes Carlos María Isidro de Borbón and his wife, María de Asís de Braganza y Borbón. The monastery was built in neoclassical style, between 1826 and 1832. On the outside, the facade is made from black and red marble, featuring the shields of Spain and Portugal, Saint Charles Borromeo, Saint Jane of Chantal and Saint Francis of Assisi. Inside the church, built in the shape of a Latin cross, there is an interesting collection of religious paintings by the Court painter, Vicente López and his school (Valencia)

Around 250 trees, such as a tulip tree, pines and giant sequoia trees, are found in the lovely Gardens of Europe, where you can enjoy a walk by the lake in a sunny afternoon. This romantic English garden, designed by Henri Porreaux in 1863, is a heavenly spot in town where children are free to play from a walking distance to the old town, while you sit on one of the benches in front of the lake.

The Byzantine and Christian Museum in Athens houses more than 25,000 artefacts from the Early Christian, Byzantine and Medieval times. Byzantine culture was almost entirely concerned with religious expression, so in the museum's collection you'll find pictures, scriptures, relief carvings, frescoes, pottery, fabrics and manuscripts.
