Kadıköy, on Istanbul's Asian side, is a vibrant district renowned for its historical charm and bustling daily life, with every street telling a unique story. Right in the heart of this district, in the Hasanpaşa neighborhood, a phoenix-like structure has risen from its ashes: Hasanpaşa Gazhanesi, now known as Müze Gazhane. Originally established as a factory producing coal gas, the complex underwent a long period of abandonment before being reborn as a thriving cultural hub for the city, complete with museums, a library, theater stages, and a lively public square. Below, you'll find the fascinating history of this transformation, what the complex offers, and all the practical details you need to know before your visit.

What is Hasanpaşa Gazhanesi and Why is it Important?
Gasworks (Gazhaneler) were industrial facilities where coal gas, produced by heating and distilling coal in closed containers, was distributed to the city's network. In the era before electricity, streetlights, homes, and workplaces were illuminated by this gas, which was also used for heating. Hasanpaşa Gazhanesi is one of Istanbul's four main gasworks; the others are Dolmabahçe, Yedikule, and Kuzguncuk. Among Istanbul cultural tours focusing on Istanbul's industrial heritage, Gazhane stands out as a primary stop showcasing the Asian side's industrial past.
The Need for Illumination on the Asian Side
In the second half of the 19th century, the Asian side of Istanbul was illuminated by gas supplied from the Kuzguncuk Gasworks starting in the 1860s. As the city expanded, the gas produced by this facility became insufficient, leading to the idea of a new gasworks. A contract signed on July 28, 1891, between Parisian iron manufacturer Charles George (known in Ottoman records as Monsieur Charles George) and Şehremini Rıdvan Pasha, granted a 50-year concession for the lighting and heating of the region extending from Kadıköy and Üsküdar along the Anatolian coast to the Beykoz border, using gas derived from coal.
From Coal to Coal Gas: How Production Worked
Architect-contractor Guglielmo Semprini began construction on August 1, 1891, and the facility commenced operations in 1892 under the name Üsküdar-Kadıköy Gas Company. Its proximity to Kurbağalıdere was no coincidence: coal brought via the stream was transported into the complex by a rail system, processed, and converted into coal gas. Equipped with the advanced engineering of its time, this production line operated continuously until World War I. During the war years, when finding hard coal became difficult, even olive pits were used to produce gas to keep production going.

From Abandonment to Müze Gazhane: A Conservation Struggle
With the widespread adoption of natural gas, the demand for coal gas dwindled, and production ceased on June 13, 1993. Subsequently, the site was used for various functions like storage, a garage, a junkyard, and a coal depot, leading to rapid deterioration of its structures. In 1994, when a decision was made to dismantle the remaining production units, the story took a dramatic turn.
Neighborhood Volunteers' Resistance
Opposition from local residents and civil society organizations halted the demolition, and the area was declared a protected site. The Gazhane Environmental Volunteers, who began organizing in 1996, transformed into a cooperative in 1998 and kept the demand for the complex to become a cultural center on the agenda for years. Festivals they organized in 2009 brought this demand into the public eye. This is why architectural circles refer to this process as a 'pioneering conservation struggle': the determined insistence of citizens behind the project was as crucial to the outcome as the project itself.
The Long Road to Restoration and the 2022 Award
The restoration project was prepared by Istanbul Technical University between 1998 and 2001, but approval from the Conservation Board was pending until 2014. The tender for the work was issued on January 8, 2014, and on-site work began on March 7, 2014. The project progressed as a collective effort involving numerous experts and students, under the consultancy of architectural historian Prof. Dr. Afife Batur, and led by Gülsün Tanyeli and Kani Kuzucular. The complex opened as Müze Gazhane on July 9, 2021, and was honored with the Building / Conservation Branch Award at the 2022 National Architecture Awards.
Architectural Fabric and Industrial Aesthetics
The first thing you'll notice upon stepping into the complex is that its industrial character has been carefully preserved. Brick walls, soaring volumes, cast-iron details, and the sheer mass of the gas production structures vividly showcase the engineering prowess of the era.
Re-functionalization Approach
The re-functionalization of the museum and library buildings, along with interior and furniture designs, was carried out by do[x]architecture. The design team adopted the principle of minimally altering the structures and preserving their existing integrity. Structural elements, machinery, and machine bases remaining from the factory era were not removed but integrated into the design. Water and moisture-resistant birch marine plywood was chosen as the primary material. This approach created one of Turkey's strongest examples of what is known globally as 'adaptive reuse'.
Functional Scheme: Two Islands, One Square
The original functions of the buildings during the factory's operation and their interrelationships served as the starting point for the new functional plan. The museum buildings, temporary exhibition space, science center, workshops, bookstore, and museum shop were conceived together to form an 'activity island.' The library, co-working spaces, and cafe were planned as a second cluster. One of the administrative buildings was transformed into a visitor information, ticket, and cloakroom area. Even technical spaces, such as the mandatory parking lot, were converted into areas suitable for concerts.
What's Inside Müze Gazhane?
The complex offers a far broader program than the word 'museum' might suggest. The following units are all situated around the same courtyard, making it easy to visit several during a single trip.
Climate Museum
Designed with the goal of becoming Turkey's first public climate center, the Climate Museum answers questions such as what climate is, how it has changed throughout history, how today's global climate change differs from past shifts, and its social and economic impacts, through written and visual content. Supported by exhibitions and talks, this section aims to raise awareness about sustainable living conditions.
Science Center and Children's Workshops
Comprising three main sections and 24 exhibition units, the Science Center addresses themes such as understanding energy, energy transformation, types of energy, the future of energy, and its impact on climate change. The integration of workshops with children's play areas, hands-on activity zones, and simulation equipment offers children the opportunity to learn through experience. This section, a popular destination for school trips, may occasionally be closed for maintenance; if you're planning a visit with children, it's advisable to check current announcements beforehand. Those who appreciate workshop culture can expand this experience with Kadıköy traditional Turkish arts tours organized in the district.
Afife Batur Library
Dedicated to academician, architect, and architectural historian Prof. Dr. Afife Batur, the library offers a selection of approximately 10,000 books across categories such as general culture, art, science, history, urban studies, ecology, architecture, philosophy, and sociology. In addition to a digital archive section, it features silent study and reading areas. The library's 24-hour accessibility has made it one of the primary study hubs on the Asian side for students, academics, and researchers.
Galeri Gazhane and Temporary Exhibitions
Bringing urban and cultural arts to the complex with temporary exhibitions, Galeri Gazhane opened its doors with Serkan Taycan's "Towards the City" exhibition. The gallery is open every day of the week except Monday; as it may be temporarily closed until a new exhibition schedule begins, checking the program before your visit is recommended.
Theater Stages and Event Program
The Istanbul Metropolitan Municipality City Theaters welcome audiences at the complex with the 301-seat Grand Stage (Büyük Sahne) and the 130-seat Square Stage (Meydan Sahne). In addition to classics, modern plays by young writers are staged, and both adult and children's plays are featured within the same season. Concerts held in the square during summer months completely transform the complex's atmosphere.
