St. Nicholas' Cathedral of Nikaia is a prominent Orthodox landmark situated on Panagis Tsaldari Avenue. The church serves as the metropolitan cathedral of the Holy Metropolis of Nikaia. It features traditional Byzantine-influenced ecclesiastical architecture common to mid-20th-century Greek urban parish churches. The interior contains ornate wood-carved iconostases and traditional wall frescoes depicting hagiographic scenes. It functions as an active center for local religious life and community charitable services. The site is located in the dense urban fabric of the Nikea district, west of central Athens.
