Ban Vichayen
Ruins of a Nobleman's House from King Narai's Era

🔄 Updated 21 Jun 2026

Lopburi is an old town with several historic sites within walking distance of each other, but Ban Vichayen tells the story of Ayutthaya's 'opening up to the West' more clearly than anywhere else, because the buildings look nothing like a typical Thai temple or prang. Walk in and you'll see red-brick walls, tall window openings, and semicircular arched doorways familiar from European buildings. It's one of the few places in Thailand where Western architecture from that era still survives.

The story behind it — who was Vichayen?

The name 'Vichayen' comes from the noble title 'Chao Phraya Vichayen' given to Constantine Phaulkon, a Greek man born on the island of Cephalonia who entered royal service in Ayutthaya under King Narai the Great. He had a gift for languages and diplomacy, climbing the ranks to become a powerful courtier and a key go-between in relations between Siam and France.

This group of buildings was built around 1685 to host the French royal embassy that came to establish friendly relations, which is why it's also called 'Baan Luang Rap Rachathut' (the royal envoys' guesthouse). Part of it later became Phaulkon's own residence. The story doesn't end well: after King Narai died in 1688, Phaulkon was arrested and executed during the change of reign. The buildings were abandoned and fell into the ruins you see today.

What to see at Ban Vichayen

The grounds split roughly into three sections, and you can walk the loop in about 30–45 minutes. The spots people photograph most are the brick arches and the church ruins, which are the signature images of the place.

The construction worth a look — brick, arches, and the European blend

What sets Ban Vichayen apart from other historic sites in Lopburi is the construction technique. Watch for these details as you walk.

• Semicircular arches — the doorways and openings are built as rounded arches, a European load-bearing technique, different from the pointed arches or straight lintels of Thai work.
• Thick plastered brick walls — heavy red brickwork like a Western building, with traces of the original plaster still visible in places.
• Tall window openings — long vertical Renaissance-style windows that let in plenty of light and air.
• Lotus-bud columns in the church — Thai craftsmanship slipped into a European church plan, a good example of two styles combined in one building.

The overall picture is hybrid architecture: the structure and technique came from Europe, but the people who actually built it were local craftsmen, so Thai details crept in. If you like photographing brick ruins and the shadows of arches, the low light of early morning or late afternoon gives the nicest depth.
