The Torre del Conde is the oldest surviving building in the Canary Islands, a squat pink-walled watchtower built around 1450 by Hernán Peraza the Elder. It stands at the edge of the bay just south of the ferry terminal, looking slightly incongruous amid the palm trees and the modern promenade, but it has been here long enough to have watched every chapter of the island's colonial history unfold.
The tower is now managed as a museum and cultural space. Inside, panels trace the Peraza family's conquest of Gomera and the tower's role in the earliest years of Spanish Atlantic expansion. The views from the roof over the harbour and across the channel toward Tenerife are worth the modest entrance fee on their own.
