Maria Theresa and Joseph II: How Trieste Was Invented in the Eighteenth Century

At the beginning of the eighteenth century, Trieste was a modest fortified settlement of barely three thousand inhabitants, huddled around the hill of San Giusto. Nothing about this sleepy Adriatic outpost hinted at the spectacular transformation that lay ahead. Within a few decades, three Habsburg sovereigns — Charles VI, Maria Theresa, and Joseph II — would turn Trieste into one of Europe's most dynamic port cities, a cosmopolitan emporium where Greek merchants, Serbian traders, Jewish financiers, and Armenian entrepreneurs lived and worshipped side by side.

Charles VI and the Gamble of the Free Port

The story begins not with Maria Theresa but with her father, Emperor Charles VI. In 1717, he issued the Patent of Free Navigation in the Adriatic, breaking Venice's centuries-old maritime monopoly. The following year, the Peace of Passarowitz (today Požarevac) secured the Empire's southeastern borders. With both sea lanes and frontiers open, on 18 March 1719 Charles VI declared Trieste a free port — a bold wager on a city whose only obvious assets were deep harbours and a strategic position at the head of the Adriatic.

The gamble paid off swiftly. To commemorate his 1728 visit, the city erected a column in Piazza San Pietro (today Piazza Unità d'Italia), initially topped with a hastily carved wooden statue. The stone column — hauled from Corgnale using forty-three oxen and seventy labourers — would receive its definitive sculpture by the Venetian artist Lorenzo Fanoli only in 1756. The emperor gazes toward the old town and points toward the sea: a gesture that symbolises the new course he set for Trieste. It is the only monument in Piazza Unità that has never moved from its original position.

Two years after his visit, in 1730, Charles VI expropriated the salt pans on the city's outskirts — a seemingly technical decision that cleared the ground, quite literally, for the urban revolution his daughter would carry out.

The Reign of Maria Theresa: Reforms and Infrastructure

When Maria Theresa ascended to the throne in 1740, she inherited an empire in turmoil but also a port city with extraordinary potential. Over her forty-year reign, she transformed Trieste from a promising outpost into a fully-fledged commercial hub.

Her key measures for Trieste included:

• Extension of free-port privileges to the entire Camerale District (1747) and then to the whole city (1769), abolishing internal customs lines
• Demolition of the medieval city walls, physically joining the old hilltop settlement with the new commercial quarters below
• Construction of essential infrastructure: a lazaret, an orphanage, an aqueduct for drinking water, and a hospital
• Founding of the Nautical School (1755), training a new generation of sailors and merchants

At the imperial level, Maria Theresa modernised the state with remarkable energy: she introduced the land registry to tax noble estates, mandated schooling for both sexes up to age twelve, and — after publishing the Constitutio criminalis theresiana in 1769 — abolished torture as a judicial instrument in 1776.

The Borgo Teresiano: A Modern City on Reclaimed Salt Flats

The most visible legacy of Maria Theresa's reign is the Borgo Teresiano, one of the first modern planned neighbourhoods in Europe. Built on the drained salt pans that Charles VI had expropriated, the quarter was laid out on a strict orthogonal grid — a rational chessboard that broke decisively with the medieval labyrinth on the hill above.

The planning was entrusted to Johann Conrad de Gerhardt, under the supervision of a commission led by Francesco Bonomo. Later, celebrated architects such as Matteo Pertsch and Pietro Nobile contributed to the quarter's refined neoclassical character.

The district's crowning engineering feat is the Canal Grande, built between 1754 and 1756 to allow merchant ships to sail directly into the heart of the commercial quarter. Goods could be unloaded at the doorsteps of the warehouses lining the canal — a logistical innovation that made Trieste's port operations remarkably efficient.

Today the Borgo Teresiano stretches between Via Carducci, Corso Italia, the railway station, and the Rive. Its landmarks include Piazza Ponterosso, the Church of Sant'Antonio Nuovo, and the striking Serbian Orthodox Temple of the Holy Trinity and San Spiridione — a tangible reminder of the religious pluralism that Maria Theresa fostered.

Tolerance and Cosmopolitanism

Free-port status acted as a magnet. Trieste's population leapt from roughly three thousand at the start of the century to over ten thousand by its end, eventually surpassing two hundred thousand in the nineteenth century. The tax exemptions and trading privileges attracted merchants from across the Mediterranean and the Balkans:

• Greeks and Serbs who built churches and established prosperous trading houses
• Jewish families who contributed to finance and culture
• Armenian and Ottoman merchants who enriched the city's commercial networks
• Croats, Slovenes, and Germans who formed the fabric of everyday life

Under the Habsburgs, these communities enjoyed freedom of worship, founding their own churches, temples, and cemeteries. The result was a city whose skyline — punctuated by Orthodox domes, Catholic spires, a synagogue, and a Lutheran church — declared its pluralism in stone and copper.

Joseph II: Radical Reform and the Borgo Giuseppino

Joseph II, Maria Theresa's eldest son, ruled from 1780 to 1790 and pushed the Enlightenment agenda further than his mother had dared. His reforms were sweeping: in 1781 he issued decrees freeing serfs and abolishing feudal privileges in territories including the Gorizian countryside. He suppressed numerous religious orders, a policy that had direct urban consequences in Trieste.

To make room for a new quarter south of the old city, Joseph II ordered the demolition of several convents — those of the Capuchins, the Misericorditi, and the Minorites — along with the ancient church of the Madonna del Mare and the cemetery of the Santi Martiri. On this cleared ground, beginning in 1788, the Borgo Giuseppino took shape, designed by the architect Domenico Corti according to the same neoclassical rationalism that characterised the Theresian quarter.

The new borough extended beyond the historic Porta Cavana toward the Lazzaretto di San Carlo. Around 1825, the waterfront was filled in to create the Rive Grumula and Rive dei Pescatori, and the district's focal point — Piazza Giuseppina (today Piazza Venezia) — emerged as a natural extension of the new quay. The square later gained two notable landmarks: Palazzo Revoltella (1858), designed by the Berlin architect Friedrich Hitzing and engineer Giuseppe Sforzi, and the Monument to Maximilian of Habsburg (1875), sculpted by Giovanni Schilling of Dresden.

Two Cities in One: The Heritage Written in Stone

Walking from the railway station through the Borgo Teresiano, across Piazza Unità, and up to the castle of San Giusto, visitors today experience a striking architectural duality. Below lies the Enlightenment city: rational grids, neoclassical facades, the broad canal, and the tolerant campanili of half a dozen faiths. Above sits the medieval town: the patched cathedral, Roman ruins, and a labyrinthine tangle of narrow streets.

This contrast is not merely aesthetic — it is ideological. The hilltop preserves what Trieste was before the Habsburgs: a small, enclosed border settlement looking inward. The flat city below embodies the Habsburg project: outward-looking, commercial, pluralist, and designed from scratch according to Enlightenment principles.

The transformation that Maria Teresa and Giuseppe II set in motion in the eighteenth century defined Trieste's identity for centuries to come. The free port, the grid of the Borgo Teresiano, the canal, the cosmopolitan communities — these are not relics of the past but the living DNA of a city that still looks to the sea and to the world beyond it.
