Situated at coordinates 60°28′N 22°02′E, Naantali is part of the
Archipelago Sea, featuring numerous islands covered in forests and
farmland, while the mainland hosts most residential areas. The landscape
includes coastal waters, rocky shores, and green spaces, ideal for
boating and outdoor activities. The area is influenced by the Baltic
Sea, contributing to its mild climate.
Naantali has a humid
continental climate with maritime moderation. Winters are relatively
mild, with average January temperatures around -3°C (27°F), and snowfall
supporting winter activities. Summers are cool and pleasant, with July
averages around 17°C (63°F), perfect for tourism. The region experiences
moderate precipitation year-round, with the archipelago providing a
scenic backdrop for sailing and island hopping.
Early Foundations and Medieval Period (1438–16th Century)
The
history of Naantali begins with the establishment of the Bridgettine
Abbey (Nådendal Abbey), part of the Order of the Most Holy Saviour
founded by Saint Bridget of Sweden in 1370. The abbey was initially
established in 1438 in Stenberga, Masku, under Swedish rule (Finland was
part of Sweden until 1809). It relocated briefly to Perniö in 1442
before settling permanently in what became Naantali in the 1440s. On
August 23, 1443, King Christopher of Bavaria (King of Sweden, Denmark,
and Norway) granted a charter allowing the construction of the convent
and endowing it with trading rights and privileges. This charter
effectively founded the town, making Naantali a key pilgrimage site and
economic center in medieval Finland.
The convent church, a medieval
stone structure built between 1460 and 1480, became the town's
centerpiece and remains one of Finland's oldest monuments. It was
consecrated in 1462 and served both monks and nuns in separate sections,
as per Bridgettine rules. The abbey attracted pilgrims and fostered
crafts like knitting, which later became a local specialty (e.g.,
knitted stockings). A notable figure from this era is Jöns Budde (c.
1435–1491), a Finnish Franciscan friar and the first named Finnish
author, who translated religious texts at the abbey.

Relocated to Perniö.
1443 (August 23): Town charter granted by King
Christopher; permanent site in Naantali.

15th Century: Becomes a major pilgrimage and
trade hub.
During this period, Naantali prospered under Swedish
rule, with the convent's privileges boosting local economy and culture.
Reformation and Decline (16th–18th Centuries)
The 16th century
brought significant change with the Protestant Reformation in Sweden.
King Gustav Vasa's reforms led to the closure of the Bridgettine convent
in 1556 (though operations lingered until 1591), stripping Naantali of
its religious significance and pilgrimage traffic. This resulted in
economic depression lasting two centuries, as the town lost its primary
source of income and influence.
Despite the decline, the convent
church survived as a parish church, and local crafts like knitting
persisted, with Naantali gaining fame for its stockings produced by
former convent members. Recovery began in the mid-18th century with the
establishment of a tollgate and customs chamber in 1756, revitalizing
trade routes and ending the stagnation.
Key Timeline:
1556–1591: Convent gradually closed due to Reformation.
16th–18th

This era
highlights Naantali's resilience, with the old town’s wooden houses
(many from the 18th century) preserving the historical fabric.
Revival and Resort Era (19th Century)
The 19th century marked
Naantali's transformation into a fashionable resort town. In 1863, a spa
was established at Cape Kalevanniemi (now part of the Kultaranta area),
attracting visitors for health and leisure, leveraging the archipelago's
scenic beauty. This period coincided with Finland's Grand Duchy status
under Russian rule (1809–1917), where Naantali benefited from improved
infrastructure.
The old town's wooden architecture flourished, with
hundreds of houses built in the 18th–19th centuries, creating a
picturesque setting that tells stories of lived history.

20th Century:
Independence, Presidential Residence, and Expansion
Finland's
independence in 1917 ushered in modernization. In 1913–1916,
industrialist Alfred Kordelin built the Kultaranta estate on Luonnonmaa
island as a summer villa. After his death in 1917, it was acquired by
the Finnish state in 1922 and designated as the official summer
residence of the President of Finland, enhancing Naantali's national
prestige.
The town expanded through municipal mergers: in 1964 with
Naantalin maalaiskunta, and in 2009 with Merimasku, Rymättylä, and
Velkua, increasing its area and population. Tourism grew with
attractions like Moomin World (opened in 1993 on Kailo island) and
cultural events such as the Naantali Music Festival (founded 1980). The
Sleepyhead Day (Unikeonpäivä) tradition, dating back centuries but
formalized in the 1950s, involves throwing a "sleepyhead" into the sea
on July 27.

Modern Developments
(21st Century to 2025)
In the 21st century, Naantali has balanced
historical preservation with economic growth. By 2025, the population
reached 20,312, with a focus on sustainable tourism, industry (e.g.,
Port of Naantali, oil refinery), and green initiatives like the planned
eFuel facility. Cultural landmarks like the Naantali Museum (housed in
18th-century buildings) and events such as the Kultaranta Talks (annual
foreign policy discussions since 2013) underscore its ongoing historical
relevance.
The town's bilingual status (Finnish and Swedish) and twin
town relations (e.g., with Nordic and international partners) reflect
its cultural ties. Historical sites, including the church and old town,
are protected, with the abbey ruins and church drawing visitors
interested in medieval history.

The Port of Naantali ranks third in Finland for goods traffic, handling archipelago sea boat traffic including the historic S/S Ukkopekka steamship cruises to Turku. Key industries include a government-owned power plant and oil refinery by Fortum and Neste. In 2025, partnerships like Liquid Wind and Turun Seudun Energiantuotanto Oy plan an eFuel facility producing 100kt of eMethanol annually, advancing green energy transitions. Amid Finland's modest economic growth of 0.3-1.0% in 2025, Naantali benefits from national investments in renewable energy and industrial electrification.
A premier summer resort, Naantali attracts tourists with its proximity to Turku and the archipelago. Major attractions include Moomin World on Kailo island, the medieval convent stone church, and the Kultaranta presidential estate. Cultural events feature the Naantali Music Festival in June, showcasing classical music, and the Sleepyhead Day carnival on July 27, where a celebrity is thrown into the sea.
