According to Pliny the Elder, the Temple of Artemis at Ephesus had 127 columns.
Pliny described the temple as exceptionally large, saying its columns were about 60 feet (18 metres) high. He also reported that 36 of the columns were richly decorated, although the exact meaning of that description is debated. The building stood at Ephesus, an important Greek city in western Anatolia, in present-day Türkiye.
The temple was rebuilt several times after earlier structures were damaged or destroyed. The version traditionally counted among the Seven Wonders was the vast marble temple begun around 550 BC under the patronage of Croesus, king of Lydia. It was later burned in 356 BC and rebuilt again.
The figure of 127 comes from an ancient literary account rather than a complete surviving architectural plan. Archaeological remains confirm the temple's monumental scale, but not every detail of Pliny's measurements can be independently checked. The number should therefore be understood as the famous ancient report associated with the wonder.
