Builder and Patron of the Arts
Euthymius is counted among the most prolific patrons of architecture and sacred art of all the archbishops of Novgorod. During his long tenure he constructed and restored a great number of churches, an effort made especially urgent by the devastating fires that swept the city in 1431 and 1442. Among the works attributed to him are churches dedicated to Saint John Chrysostom, the Guardian Angel, and the Twelve Apostles, as well as a church of John the Forerunner.
At his own monastery of Vyazhishchi he raised a stone church in honor of Saint Nicholas in 1438 and another dedicated to Saint John the Theologian in 1439. He is also credited with the Palace of Facets (the Faceted Chamber), built in 1433, which stands northwest of the Cathedral of Holy Wisdom and survives as one of the most notable monuments of his archiepiscopal building program.
