Medieval Meets Modern: Urban Explorer's Guide to Turku's Hidden Corners

The beauty of exploring Turku lies in its manageable scale – this is a city best discovered on foot or by bicycle. My urban expedition began at the imposing Turku Castle, Finland's largest surviving medieval building, where the massive granite walls tell stories dating back to the 1280s. Rather than rushing through the tourist hotspots, I spent an hour simply walking the perimeter, noticing how the structure's various additions reflect different historical periods.

From there, I followed the Aura River eastward, using it as my natural navigation system. The riverside path offers a perfect chronological journey through Turku's architectural evolution. Medieval stone buildings gradually give way to neoclassical elegance, then functionalist designs, and finally to striking contemporary structures.

One of my favorite discoveries was the Funikulaari – Turku's quirky hillside funicular that connects the river valley to Kakolanmäki hill. As someone who's documented cable cars worldwide, I found this 2019 addition charming despite its modest 132-meter track. It's free to ride and offers spectacular views across the city's rooftops. The contrast between this modern transport solution and the former prison complex at the top of the hill perfectly encapsulates Turku's blend of heritage and forward-thinking urban planning.

For those wanting to capture Turku's architectural contrasts, I recommend the compact camera I used throughout my trip. Its excellent low-light performance was particularly valuable inside Turku Cathedral and for evening shots along the illuminated riverbank.

My fascination with post-industrial spaces drew me to Kakolanmäki, where Turku's former prison complex has undergone a remarkable transformation. Having documented similar conversions in Sheffield and across Europe, I was keen to see Finland's approach to adaptive reuse.

Kakola Prison, operational until 2007, now houses apartments, restaurants, a brewery, and even a luxury hotel. The contrast between the imposing granite walls and contemporary Finnish interior design creates a fascinating dialogue between past and present. I spent hours photographing the thoughtful architectural details – original cell doors repurposed as design elements, former exercise yards transformed into community gardens.

The Kakola Brewing Company offers tours that combine the building's penitentiary history with craft beer tasting. Their taproom, set in former prison facilities, maintains much of the original industrial character while adding warmth through wooden furnishings and subtle lighting.

Most impressive is the Kakola Hotel, where former cells have been converted into stylish accommodations. I couldn't resist booking a night here, finding the juxtaposition of luxury amenities within the historic prison walls both thought-provoking and surprisingly comfortable.

During my exploration, I relied heavily on my portable power bank to keep my phone and camera charged throughout the day. With limited charging options while exploring abandoned corridors and former prison yards, having reliable backup power was essential.

While Turku's main streets offer plenty to explore, the city reveals its most intimate secrets within the hidden courtyards of its medieval quarter. Armed with my trusty pocket guidebook and recommendations from local architecture students I met at Café Art, I ventured beyond the obvious thoroughfares.

The Brinkkala Courtyard near the Old Great Square (Vanha Suurtori) became my favorite discovery. Entering through a narrow passage that I nearly missed, the courtyard opened to reveal a tranquil space surrounded by buildings from different eras, their facades telling stories of Turku's evolving architectural identity. In spring, the courtyard comes alive with small market stalls and the first outdoor seating of the season.

Nearby, the Handicrafts Museum (Luostarinmäki) preserves an entire quarter of wooden buildings that survived the Great Fire of 1827. Unlike many European open-air museums that relocate historic structures, these buildings stand in their original locations. Wandering the narrow lanes between these wooden craftsmen's homes offered a glimpse into pre-industrial urban life that felt remarkably authentic.

Most tourists never venture into the residential courtyards along Hämeenkatu, but after respectfully asking permission from a local resident, I was invited to see several interconnected yards where medieval foundations support 19th-century wooden structures. These spaces, neither fully public nor private, represent a distinctly Nordic approach to communal urban living that fascinated me as an urban planning enthusiast.

The narrow passageways between courtyards often feature unexpected street art – not the commissioned murals found in many European cities, but smaller, more intimate expressions that feel like visual conversations between residents and visitors willing to look closely.

No urban exploration of a Finnish city would be complete without experiencing its sauna culture, and Turku offers some fascinating interpretations of this national tradition. While Helsinki might be more famous for its public saunas, Turku's riverside facilities offer a more intimate connection between urban space and wellness rituals.

My most memorable discovery was Saaronniemen Sauna, a public facility located where the Aura River meets the archipelago waters. Unlike tourist-oriented saunas, this is where locals gather, making it an excellent opportunity to experience authentic Finnish bathing culture. The contrast between the hot sauna and the bracing spring waters of the river creates a sensory experience deeply connected to the landscape.

For something more centrally located, I spent an evening at Café Sauna, where a renovated public bath from the 1950s now houses both a traditional Finnish sauna and a stylish café. The building's mid-century architecture has been thoughtfully preserved, creating a space that honors Turku's more recent heritage while maintaining its original function.

Most surprising was discovering the sauna culture within Turku's student community. Through a local contact at the university, I was invited to a sauna evening at one of the student housing complexes, where the communal sauna serves as both wellness facility and social hub. These spaces rarely appear in guidebooks but offer insight into how traditional practices evolve in contemporary urban contexts.

For these sauna expeditions, my quick-dry travel towel proved essential – compact enough to carry throughout the day yet absorbent enough for multiple sauna sessions.

Beneath Turku's surface lies another dimension of the city – both literally and figuratively. My exploration of underground spaces began at the Aboa Vetus museum, where archaeological excavations have revealed medieval streets and building foundations now preserved beneath a contemporary art museum. Walking through these subterranean passages, touching walls built in the 14th century while contemporary art installations create thought-provoking juxtapositions above, epitomizes Turku's layered identity.

Beyond physical underground spaces, I sought out Turku's alternative cultural scene. The city's status as former European Capital of Culture has left a legacy of creative energy that thrives in unexpected venues. The repurposed industrial spaces along the eastern riverbank host everything from experimental theater to electronic music events, often announced only through local social media channels or handmade posters.

Barker Park, built on the site of a former cotton mill, exemplifies how industrial heritage can be reimagined as creative space. During my visit, a temporary sound installation occupied the preserved brick chimney, transforming this industrial relic into an acoustic instrument that responded to changing weather conditions.

My most serendipitous discovery came through following a group of local students to an unmarked door near the river. Inside, I found a volunteer-run cinema showing Finnish experimental films from the 1960s, projected onto the wall of what was once a grain storage facility. These spaces don't appear in conventional tourist literature but represent the authentic cultural undercurrents that make Turku fascinating for urban explorers.

Navigating these alternative spaces after dark required reliable illumination, and my compact headlamp proved invaluable for exploring dimly lit underground passages while keeping my hands free for photography.
