Borusan Contemporary: World-Class Art Inside a Haunted Bosphorus Mansion

What Is Borusan Contemporary?

Borusan Contemporary is the contemporary art and collection initiative of the Borusan Kocabıyık Foundation, and it operates inside one of the most unusual art venues in Istanbul. The space occupies Perili Köşk, a century-old mansion in the Rumelihisarı neighborhood of Sarıyer, on the European shore of the Bosphorus. From Monday to Friday, the building functions as the corporate headquarters of Borusan Holding. On Saturdays and Sundays, it opens to the public as a full contemporary art museum. That split identity shapes everything about the experience.

The museum opened in 2011, signaling its ambitions from the start. This was not intended as a regional curiosity, but as a serious institutional statement about Turkish contemporary art and its place in the global conversation. The collection focuses heavily on video art, digital media, and new-media installations, areas where few institutions in Turkey were investing at the time of its founding.

The Building: Perili Köşk and Its History

Perili Köşk translates loosely as 'haunted mansion' in Turkish, and the nickname has stuck for decades. The Yusuf Ziya Paşa Mansion, as it is formally known, was built in the late Ottoman period, with timber-framed architecture, high-ceilinged rooms, and a position that seems to hover over the Bosphorus strait. The building's slightly dramatic silhouette against the water and the wooded hillside behind it earned it the supernatural nickname long before it became an art space.

Borusan Holding restored and repurposed the mansion as both corporate headquarters and, eventually, a public cultural institution. The tension between those two identities is visible when you arrive: reception staff check you in with the efficiency of an office building, but the rooms beyond are filled with projection works and sound installations that feel entirely at odds with any corporate environment. That contrast is part of what makes the place memorable.

The building is architecturally significant in its own right and sits close to another landmark with a more explicit historical pedigree: the Rumeli Fortress is visible from the surrounding area. The neighborhood of Rumelihisarı takes its name from that fortress, and the combination of Ottoman military history and contemporary art within a few hundred meters of each other is distinctly Istanbul.

The Collection and Exhibitions

The permanent collection at Borusan Contemporary is one of the most focused in Turkey for new-media and video art. Works by major Turkish artists sit alongside international pieces, and the curatorial perspective consistently favors conceptual depth over decorative appeal. If you come expecting conventional painting galleries, you will be surprised: screens, projections, soundscapes, and interactive installations dominate the rooms.

Temporary exhibitions rotate regularly, so the experience changes significantly from month to month. The combination of permanent collection works with rotating shows means that the ground floor presentation can feel quite different from one visit to the next. Checking the official website before your visit is useful here, not just a formality. Some temporary exhibitions also use the terraces and outdoor areas, which dramatically expands the sensory experience on a clear day.

Sound is a more prominent element of the collection than at most Istanbul museums. Several rooms contain works where the audio component is as important as the visual, so expect to slow down and spend time in individual spaces rather than moving quickly from piece to piece. Headphones are sometimes provided; sometimes the sound is ambient. Either way, this is not a museum where you cover the collection in 20 minutes.

The Bosphorus Setting: What It Actually Looks and Feels Like

The location does a great deal of the work here. Rumelihisarı is not a central Istanbul neighborhood, and the journey itself, whether by dolmuş along the coast road or on foot from a bus stop with the water visible to your right, puts you in a different headspace before you arrive. The Bosphorus at this point is relatively narrow, and the opposite shore feels close enough to study with the naked eye.

The terraces at Borusan Contemporary are underrated even by visitors who know the collection well. Midday light in summer is harsh and bright off the water, but morning visits, especially in spring and early autumn, offer soft conditions where the hillside behind the building, the water in front, and the sound of passing boats combine into something genuinely atmospheric. Sunset visits, possible only in summer when daylight extends past 18:00, can be spectacular, though you are working against the last-entry cutoff.

For context on how this Bosphorus stretch compares to other vantage points in the city, the Istanbul viewpoints guide covers the full range of perspectives from both shores. Borusan Contemporary occupies a unique position: it is simultaneously one of the better Bosphorus views in the city and a serious art institution, which is a rare combination.

Getting There and Practical Logistics

Reaching Borusan Contemporary requires a little more effort than visiting a museum in Sultanahmet or Beyoğlu, and that is worth accounting for when you plan your day. The address is Baltalimanı Hisar Caddesi No:5, Rumelihisarı, Sarıyer. The closest public transport reference point is the Boğaziçi Üniversitesi stop, from which the mansion is approximately a 9-minute walk down toward the water. Dolmuş (shared minibuses) running along the Bosphorus coastal road also stop in Rumelihisarı and are often the most practical option if you are coming from Beşiktaş or Ortaköy.

There is no on-site parking, and the narrow coastal road can be congested on weekend afternoons, so arriving by private car adds unpredictability to the journey. Taxis and ride-hailing apps work well but can be slow to reach the pickup point on the coast road after your visit. Budget extra time for the return journey if you have a fixed onward commitment.

Combining a visit to Borusan Contemporary with the nearby Rumeli Fortress makes good geographic sense, as both are within comfortable walking distance in Rumelihisarı. The fortress is a very different kind of experience, outdoor, historically specific, and without an admission requirement to the museum, but the pairing gives you a full afternoon on this stretch of the Bosphorus.

Photography, Timing, and Who Should Reconsider

Photography policies inside the galleries can vary by exhibition and should be confirmed on arrival. The terraces and exterior are generally open to photography, and the Bosphorus framing from the upper level is strong in most lighting conditions. Morning visits on Saturday tend to be quieter than Sunday afternoons, which draw more local weekend visitors. If you prefer more time and space with individual works, arriving close to the 10:00 opening is reliable.

Weather matters more here than at most Istanbul museums because the outdoor terraces and the building's relationship to the water are integral to the experience. Rain is not a reason to cancel, but it does flatten the Bosphorus views and closes off the terraces. Istanbul's autumn and spring tend to be optimal for combining the interior collection with outdoor time.

Visitors who find contemporary and new-media art inaccessible or unengaging are likely to feel that the journey is not justified by the content. The collection does not include Ottoman miniatures, Byzantine mosaics, or historical artifacts. It is focused and deliberately contemporary in both form and concept. If your priority is historical depth, other institutions in the city will reward you more directly.

For those who want to build a fuller contemporary art itinerary, Istanbul Modern on the Karaköy waterfront and the Pera Museum in Beyoğlu are the other major institutional reference points. Borusan Contemporary is more niche, more adventurous in its programming, and significantly more removed from the tourist circuits, which is either a feature or a drawback depending on what you are looking for.
