Santorini is reported to have several hundred churches and chapels scattered across an island of roughly 15,000 residents — far more than any single congregation could need. Many are tiny, single-room chapels, often privately built and maintained by individual families rather than the wider church.
A tradition of personal chapels
Historically, many of these small chapels were built by families in fulfilment of a religious vow — in thanks for a safe return from a voyage, recovery from illness, or another personal event — rather than as public places of worship. Most open only once a year, on the feast day of the saint they're dedicated to, when the family that maintains them hosts a small celebration.
The blue domes
The blue-domed white churches that appear in nearly every photo of the island are a relatively recent architectural convention — many were rebuilt or repainted in the mid-20th century, after earlier earthquake damage, in the blue-and-white palette that's now inseparable from Santorini's image. Older churches on the island show a wider range of colours and styles.
Visiting respectfully
Most chapels are simple, unstaffed buildings — if you find one open, modest dress and quiet behaviour are appreciated, as they remain active places of worship rather than tourist attractions, even when nobody else is around.
