Temanza gave Venice a church on the plan of the Pantheon and set above its door a triangle with an eye inside it. Two and a half centuries later people still stop in the campo to argue about what it means.
At a glance
A church stood here from the thirteenth century, founded by tradition in 1222 by the Baffo family. Nothing of it survives. The architect and architectural historian Tommaso Temanza (1705–1789) drew a complete rebuilding, approved in 1758, and the church as it stands went up between 1763 and 1790 — Temanza did not live to see it finished. It is one of the most advanced neoclassical buildings of its moment anywhere in Europe, and it sits in a small campo in Cannaregio where almost nobody looks for one.
What you see
A cylinder under a hemispherical dome, fronted by a columned porch with a pediment, the one straight line in a building made of curves. Inside, the circle turns into a hexagon: paired columns at each angle, marble cornices, niches with devotional statues, and four chapels on the radial axes. Above the portal runs the frieze that everyone photographs — a triangle with an eye at its centre, and the words SAPIENTIA AEDIFICAVIT SIBI DOMUM, wisdom has built herself a house, from the Book of Proverbs.
Why it matters
Venice built one other round church, San Simeon Piccolo, and then stopped. Both look to the Pantheon over the heads of two centuries of Venetian Baroque. The eye in the triangle is a Christian image of the Trinity long before it is anything else, but Temanza moved in the enlightened, lodge-going Venice of the 1760s, and the reading has stuck. The Italian Environment Fund puts it carefully: some of the inscriptions and images here are of difficult interpretation. That is the honest position, and it is more interesting than a verdict.
Practical information
- Opening is irregular and the church is often closed; the portal, the frieze and the inscription are outside and can be seen at any hour
- The campo is small and quiet, a minute off the Strada Nova
Getting there
Waterbus to San Marcuola or Ca’ d’Oro, then three minutes on foot. The church faces Campo de la Maddalena, just off the Strada Nova.
