Early Urban Development: Camulodunum, Fishbourne and Aquae Sulis

Camulodunum (Colchester) and the Temple of Claudius

The very first Roman capital in Britain had no defensive walls, a fatal flaw that would eventually lead to its fiery destruction. Originally an Iron Age oppidum (Camulodunon), the site was initially repurposed as a fortress for the 20th Legion (Legio XX Valeria Victrix). In AD 49, it was converted into Britain's first colonia (Colonia Claudia Victricensis).

• Infrastructure: The military grid was repurposed, transforming barracks into civilian houses. The new capital featured a forum, a curia (council chamber), a theatre, and the only known chariot circus in Roman Britain.
• The Temple of Claudius: The centerpiece of the city was the Templum Divi Claudii, dedicated to the deified Emperor Claudius. It was the provincial center for the Imperial Cult.
• Architectural Features: It was the largest classical temple in Britain. It featured an octastyle design (8 columns at the front, 11 on the sides) with a pronaos (porch) and a cella (inner chamber). The massive podium measured 80 ft by 105 ft and stood 11 ft high. To conserve stone, Roman engineers built four sand-filled vaults inside the podium. The temple was surrounded by a sacred precinct called a temenos, accessed via a monumental arch faced with tufa stone.

This grand temple caused immense social friction. Tacitus described it as a "citadel of eternal tyranny," noting that native priests were forced to bankrupt themselves to maintain the Imperial Cult. The philosopher Seneca even mocked the temple in his satire Apocolocyntosis, ridiculing the idea of Britons worshipping Claudius. During the Boudiccan Revolt (AD 60/61), the unfortified city was attacked. Survivors held out in the temple for two days before it was sacked, leaving a distinct burnt layer still visible in excavations today.

Fishbourne Roman Palace and King Cogidubnus

Just how lavishly did the Romans reward their most loyal local allies? The site at Fishbourne transformed dramatically from a simple military supply base in AD 43 to an unprecedented display of luxury. By c. AD 60–65, it had developed into a stone-walled 'proto-palace' with a bath suite, before becoming the magnificent Flavian 'Great Palace' between AD 75–80.

• Scale and Luxury: Covering 2.3 hectares, the Great Palace was the largest Roman residence north of the Alps. Builders moved roughly 360,000 cubic feet of soil just to level the site.
• Architecture: It featured four wings surrounding a massive 75m by 100m formal garden with a colonnaded walkway. The palace was decorated with over 50 mosaics, shifting from 1st-century geometric patterns to intricate 2nd-century designs like 'Cupid on a Dolphin'.
• Status Indicators: The West Wing Audience Chamber was built on a platform 1.5m higher than the surrounding rooms to physically elevate the ruler above his guests. The site featured imported marble, Pompeian-style frescoes, and decorative opus sectile floors.

This palace is strongly associated with Client King Tiberius Claudius Cogidubnus, the ruler of the local Regni tribe. His status is confirmed by the Chichester Inscription, which names him Rex et Legatus Augusti in Britannia (King and Imperial Legate). The Romans granted him citizenship and the Emperor's name in exchange for his loyalty. Tacitus confirms this strategy in Agricola 14, describing Cogidubnus as a "most faithful ally" who the Romans successfully used as a tool to manage the native population.

Aquae Sulis (Bath) - Temple and Baths

Every time you visit a modern spa, you are participating in a relaxation ritual that the Romans perfected over two thousand years ago. Founded shortly after AD 43 at the junction of the Fosse Way and the River Avon, Aquae Sulis was built around a natural hot spring producing over 1,170,000 litres of water daily at a scorching 46°C.

• The Baths: Roman engineers enclosed the spring in a lead-lined stone reservoir. The complex featured a Great Bath with a 1.5m deep lead-lined pool, originally covered by a towering 20m high barrel-vaulted roof. Hot rooms (caldaria) were heated using an underfloor hypocaust system.
• Religious Syncretism: The site was a masterclass in syncretism — the blending of cultures. The Romans merged the local Celtic water goddess Sulis with their own goddess of wisdom, creating Sulis Minerva. Her classical, Corinthian-columned temple housed a gilded bronze statue of the deity.
• Hybrid Art: The temple's pediment famously displays a Gorgon's head. Unlike traditional female depictions of Medusa, this is a uniquely Romano-British male Gorgon with a beard intertwined with snakes.
• Social Evidence: Aquae Sulis functioned as a major international religious sanctuary and leisure center. The tombstone of a Gallic woman named Rusonia Aventina proves it attracted international pilgrims. Furthermore, over 130 lead and pewter defixiones (curse tablets) have been recovered from the spring, usually written in Latin by visitors asking the goddess to punish petty thieves. A stone carving of a boar found at the site suggests the 20th Legion assisted in its construction.
