The National Archaeological Museum is one of the largest museums in Greece and one of the world's great museums. Although its original purpose was to secure all the finds from the nineteenth century excavations in and around Athens, it gradually became the central National Archaeological Museum and was enriched with finds from all over Greece. Its abundant collections, with more than 20,000 exhibits, provide a panorama of Greek civilization from the beginnings of Prehistory to Late Antiquity.
The construction of the museum's building began in 1866 and was completed in 1889. The museum has an imposing neo-classical design which was very popular in Europe at the time and is in full accordance with the classical style artifacts that it houses. It was designed by L. Lange and remodelled by Ernst Ziller. It has a vast exhibition space with numerous galleries on each floor accounting for a total of 8,000 square meters.
