The Church of Panagia Chrysospiliotissa is a three-nave domed basilica with a transept, narthex and an upper room. It was built on the site of an older church, a small basilica. The church was designed by D. Zezos, but its construction began in 1863, six years after his death, under the direction of P. Kalkos. After Kalkos's death, the continuation of the construction was entrusted to Ernest Ziller, but the church commissioners and parishioners did not accept Ziller's proposed changes to the church design and entrusted the project to the mayor of Athens and the civil engineer Dimitris Soutsos.→
