By the 7th century BCE, builders in coastal Ionia and the Aegean islands began experimenting with column bases and capitals that anticipate the later canonical Ionic order, setting the stage for its mature form in monumental temples.
A 7th-century BCE successor temple at the Heraion of Samos introduced notable colonnade innovations—reported as the first temple with a double row of columns across the front—a key step toward the large-scale Ionian temple tradition tied to the Ionic order’s development.
Construction began on the so-called Rhoikos Temple (by Rhoikos and Theodoros) at Samos, widely cited as among the earliest monumental temples in the emerging Ionic order tradition, helping standardize large-scale columnar design in Ionia.
The Rhoikos Temple at the Heraion of Samos was completed around the mid-6th century BCE, representing a decisive move toward monumental, repeatable Ionic temple design in the Ionian world.
The Rhoikos Temple stood only about a decade before being destroyed (often attributed to instability or earthquake-related failure). Its short life did not prevent its outsized influence on later Ionic temple experiments in Ionia.
A major reconstruction of the Temple of Artemis at Ephesus began around 550 BCE, sponsored at least in part by Croesus of Lydia and designed by Chersiphron (and Metagenes). The project advanced the Ionic order through unprecedented scale, marble construction, and elaborate column programs.
By the 5th century BCE, Ionic columns and details were increasingly used in mainland Greece, including Athens, marking a shift from a primarily Ionian regional tradition to a pan-Hellenic architectural vocabulary.
The Propylaea, the monumental gateway to the Athenian Acropolis, was built in 437–432 BCE. Despite its strongly Doric exterior, it incorporated Ionic columns in the interior, signaling Ionic’s prestige within major Athenian state architecture.
The small Ionic temple on the Ilissos River (traditionally dated to the mid-5th century BCE) is often placed around 435–430 BCE and is noted for an Attic Ionic base profile (including a scotia between tori), reflecting ongoing Athenian refinement of Ionic details.
The Temple of Athena Nike on the Acropolis bastion was constructed between 427 and 424 BCE. As a small but highly influential Ionic temple in a prominent civic-religious setting, it helped define an Athenian Ionic idiom alongside larger Acropolis projects.
Construction of the Erechtheion—an Ionic temple with complex planning to accommodate multiple cults and uneven terrain—began in 421 BCE, becoming a landmark synthesis of Athenian Ionic proportions, ornament, and inventive spatial composition.
The Erechtheion was completed by 406 BCE. Its Ionic porches, rich moldings, and the celebrated south porch (with Caryatids) made it a defining Classical statement of Ionic architecture in Athens.
In 356 BCE, the Temple of Artemis at Ephesus was destroyed by a fire attributed in ancient tradition to the arsonist Herostratus. The loss of this major Ionic monument underscored both its fame and the continuing cycle of rebuilding that shaped Ionic architectural history.
The Mausoleum at Halicarnassus (built ca. 353–351 BCE) was designed by Satyros and Pythius of Priene. While not a canonical temple, it exemplifies the broader Ionian/Classical design milieu that influenced late Classical architectural thinking, including Ionic refinement and monumental presentation.
The Temple of Athena Polias at Priene (ca. 350–330 BCE), attributed to Pytheos/Pythius, was recognized in antiquity and later scholarship as a key exemplar of pure Classical Ionic style, helping codify Ionic proportions and detail in the late Classical period.
After Alexander’s campaigns reopened the Ionian cities’ horizons, planning for a new, colossal Temple of Apollo at Didyma began after 334 BCE. The project deployed a double file of towering Ionic columns and a distinctive plan, extending Ionic monumentality into the Hellenistic era.
