The three Trilithon blocks at Baalbek are among the largest stones moved in antiquity. Each block is about 19 metres (62 feet) long—not 19 metres high—4.2 metres (13.8 feet) high, 3.6 metres (11.8 feet) thick and roughly 750–800 tonnes. They form part of the Temple of Jupiter complex and are generally interpreted as the podium or base of a smaller temple. The video presenter compares them with megaliths at Tiwanaku in Bolivia and Caral in Peru.

Key facts
- The three blocks are approximately 19 metres (62 feet) long, 4.2 metres (13.8 feet) high and 3.6 metres (11.8 feet) thick. The 19-metre figure is their length, not their height.
- Each block weighs roughly 750–800 metric tonnes. They are widely described as among the largest stones moved in antiquity, but the supplied results do not confirm the precise largest, third-largest and tied-fifth-largest ranking.
- The trilithon is part of the Temple of Jupiter complex and is generally interpreted as the podium or base of a smaller temple.
- The comparison with Tiwanaku in Bolivia and Caral in Peru is the video presenter's comparison, not an established shared construction tradition.
