Map of the island of Taiyouan, opposite the coast of Formosa

The map shows Taiyouan, the sandy island in front of the coast of Formosa (present-day Taiwan), where the VOC had built Castle Zeelandia in 1624, and where the eponymous city developed in subsequent years. An extensive legend (A through M) shows the different buildings and quarters of the city, several anchorages for ships, sand banks and dunes.
