As a major landmark, the Titan is often used as a symbol of the city itself. The image of the Titan appears on Braavosi coinage.
In the books
In the A Song of Ice and Fire novels, the Titan of Braavos is a massive stone and bronze statue that guards the entrance into the lagoon where Braavos is situated. It is the primary line of defense for Braavos and lets out a loud blast whenever a ship approaches the entrance to warn the Arsenal of its coming.
The Titan was likely inspired by the real-life Colossus of Rhodes, an allegedly gigantic statue of the Greek sun god, Helios, that graced the harbor of Rhodes in the Aegean Sea. Listed as one of the Seven Wonders of the Ancient World, it was destroyed during an earthquake in 226 BCE. Later artistic impressions show the Colossus as straddling the harbor with an upraised arm, much like the Titan, but it is generally accepted that this was a misinterpretation that originated in the medieval period. The actual Colossus probably stood to one side of the harbor in a posture that was structurally sound for its heavy bronze composition.
