Trdat the Architect (Armenian: Տրդատ ճարտարապետ, circa 940s – 1020; Latin: Tiridates) was the chief architect of the Bagratuni kings of Armenia, whose 10th century monuments have been argued to be the forerunners of Gothic architecture which came to Europe several centuries later.

In 961, Ashot III moved his capital from Kars to the great city of Ani where he assembled new palaces and rebuilt the walls. The Catholicosate was moved to the Argina district in the suburbs of Ani where Trdat completed the building of the Catholicosal palace and the Mother Cathedral of Ani. This cathedral offers an example of a cruciform domed church within a rectangular plan.

After a great earthquake in 989 ruined the dome of Hagia Sophia, the Byzantine officials summoned Trdat to Byzantium to organize repairs. The restored dome was completed by 994.  Trdat is also thought to have designed or supervised the construction of Surb Nshan (Holy Sign, completed in 991), the oldest structure at Haghpat Monastery.

Maranci, Christina in The Architect Trdat: Building Practices and Cross-Cultural Exchange in Byzantium and Armenia writes

«In the Armenian source star of the beginning of  XI century — «Universal history»  of StepannosTaroneci — we find his (Trdat’s) name.

Search for more specific information on the contribution of Tiridat was one of the objectives of the archaeological research, William Emerson and Robert l. Van Najsa.
Publications in series 40-50s two scientists have presented a detailed account of the construction of the second of the dome of St. Sofia by Isidor junior and post-earthquake X and XIV centuries. Half a century later, no one questioned their scientific results. »
