Thai Khu Fah, Bangkok — a Venetian Gothic palace as the seat of a government

Bangkok, Thailand · reign of Rama VI · Government building

At a glance

The seat of the Prime Minister of Thailand is a Venetian Gothic palace. The Thai government’s own account says the building was modelled on the Ca’ d’Oro, the fifteenth-century house on the Grand Canal in Venice, and the resemblance is not a matter of atmosphere: the upper floor carries the same continuous screen of pointed, interlaced tracery. It was built as a private house called Ban Norasingha, in a city eight thousand kilometres from the lagoon, and it was one of the works produced in Siam by the Italian architects, engineers and artists whom Rama V and Rama VI brought into government service.

What you see

From the road the building is long and low, in ochre and cream under a red tiled roof, behind green railings with gilded panels. The upper floor is a continuous arcade of pointed arches with interlaced tracery and quatrefoils, run end to end like a screen rather than punched as windows — the Ca’ d’Oro device, transplanted. At the left end a square tower carries an open loggia and a gilded spire with the Thai flag above it. At the right, a dome sheathed in gold sits on a drum of tall traceried openings, and finials in the shape of Thai flame ornaments rise between them. That dome is where the Venetian model stops and something else begins.

At dusk, with the lamps on and rainwater standing on the forecourt, the whole elevation doubles in the reflection and the tracery reads twice. It is the view the building was composed for, and it makes the point better than any argument: a Venetian palace front, in Bangkok, with a Thai roofline, doing the work of a national government.
