At a time when Salvador was the biggest port in South America and Portugal still vied with Spain and Holland for the title of world's richest empire, the sugar barons of Salvador decided to splurge a little and let folks know that their colony had arrived. Beginning in 1708 and continuing until 1723, they took more than 100 kilograms of gold and slathered it over every available knob and curlicue in the richly carved interior of this high-baroque church. The result could hardly be called beautiful -- works of the nouveaux riches seldom are -- but by God, it's impressive. The inside fairly gleams; on nights when the doors are open it casts a yellow sheen all the way up to Terreiro de Jesus. If you can, time your visit on a Tuesday toward dusk (5:30pm-ish). The church will be packed with parishioners coming for a blessing, while outside wealthy matrons seeking the special favor of Saint Francis will be passing out little loaves of bread to a veritable mosh pit of Salvador's poor. On Monday, Wednesday, and Saturday, at 11:30am and 4pm, is an impressive sound-and-light show in the church.
Next door, the Ordem Terceira de São Francisco church (Mon-Fri 8am-noon and 1-5pm) has a gorgeous sandstone facade on the outside, and on the inside some fine blue tile and a rather silly hall of saints. Allow an hour for both churches.
