In the 19th century, during an architectural revival that looked back to Armenia's past, the plan of Etchmiadzin Cathedral began to be directly copied in new Armenian churches. Some notable examples from this period include the narthex of the St. Thaddeus Monastery in northern Iran, dating from 1811 or 1819 through 1830, and the Ghazanchetsots Cathedral in Shusha, dating from 1868. Its plan was also replicated in the Armenian diaspora. One example is the Armenian Church of Bucharest, Romania, designed by Dimitrie Maimarolu and built in 1911–12.
