Turkish television is heading into a new drama season with Mercan Köşk, and the series has just added another familiar face to its growing ensemble. Hazal Çağlar, widely recognized for her role as Asuman in Gönül Dağı, will join the ATV drama as Oya, an ambitious lawyer whose arrival is expect to add another layer of tension to the story.
Produce by FARO and Sinehane, Mercan Köşk is set against the atmospheric backdrop of Tarsus in Mersin. The series stars Hafsanur Sancaktutan, Kubilay Aka and Bertan Asllani at the center of a story shaped by family conflict, hidden secrets, revenge and complicated relationships. ATV has confirmed that the series premieres on Saturday, September 5, 2026, at 8:00 p.m.
For viewers already following the production, Hazal Çağlar’s addition could become one of the more intriguing developments around the early episodes.
Hazal Çağlar Takes on the Role of Oya
According to Turkish entertainment journalist Birsen Altuntaş, Hazal Çağlar will portray Oya, an ambitious lawyer who enters the story in the second episode of Mercan Köşk. Her character is expect to increase the dramatic pressure surrounding the central characters.
The casting is particularly interesting because Çağlar arrives with strong recognition from Gönül Dağı, where her portrayal of Asuman helped establish her among Turkish television audiences. Moving from that long-running series into a more tension-driven drama gives the actress an opportunity to explore a different kind of character.
Oya’s profession also creates possibilities for the storyline. A lawyer naturally operates around disputes, evidence, legal pressure and conflicting interests elements that fit comfortably into a drama built around secrets and family confrontations.
What Is Mercan Köşk About?
At its heart, Mercan Köşk revolves around Cemre, played by Hafsanur Sancaktutan, whose life changes dramatically after the mysterious disappearance of the man she has just married.
Her search for answers eventually brings her to Tarsus and the mysterious Mercan Köşk, where she becomes entangled in the complicated history of two rival families.
ATV describes the series as a story combining secrets, long-standing family conflicts, sacrifice and an impossible love. Cemre’s arrival disrupts the carefully constructed world of Aras, played by Kubilay Aka, while buried secrets begin threatening the fragile balance between the families.
That foundation gives the series plenty of room to introduce secondary characters who can influence the central conflict and Oya appears to be position as one of them.
Why Oya Could Matter to the Story
The arrival of Oya in episode two is more than a simple casting addition. Introducing an ambitious lawyer into a story dominated by family secrets could provide Mercan Köşk with a fresh perspective on its central conflicts.
Rather than relying exclusively on emotional confrontations, the character could potentially bring a more strategic dimension to the narrative. Her professional background may place her in situations where personal interests, legal questions and family loyalties collide.
That is especially relevant in a series where characters are already carrying secrets from the past.
Of course, the exact nature of Oya’s connection to Cemre, Aras and the other families remains something the series will reveal on screen. For now, the confirmed detail is that Hazal Çağlar joins the production from its second episode onward as Oya.
A Strong Setting for a High-Stakes Drama
Another major attraction of Mercan Köşk is its setting. The series has film in Tarsus, Mersin, using the region’s historic architecture, landscapes and atmosphere as an important part of its visual identity.
ATV has highlighted Tarsus and the surrounding Çukurova atmosphere, including the area’s orange groves, as part of the show’s distinctive visual world.
The production is directed by Yahya Samancı, with the original story created by Ahunur Serdaroğlu. The writing team includes Serdaroğlu alongside Atilla Özel, Nalan Merter Savaş and Nuriye Bilici.
This combination of a strong ensemble, an atmospheric location and a story built around rival families gives Mercan Köşk the ingredients of a traditional Turkish prime-time drama while leaving space for modern character conflicts.
When Does Mercan Köşk Premiere?
The first episode of Mercan Köşk is scheduled for Saturday, September 5, 2026, at 8:00 p.m. on ATV.
Hazal Çağlar’s Oya, meanwhile, is expected to enter the story with the second episode, giving audiences another reason to keep watching after the opening chapter establishes Cemre’s journey and the show’s major conflicts.
For fans of Hazal Çağlar, the casting also represents an exciting new chapter following her popularity as Asuman in Gönül Dağı. Her transition into the role of Oya could prove particularly compelling if the character becomes closely connected to the legal and personal battles unfolding inside Mercan Köşk.
Final Thought
Mercan Köşk is clearly building its world around secrets, family power struggles and emotional uncertainty. Adding Hazal Çağlar as Oya gives the drama another intriguing character just as its central conflicts begin to take shape.
Her arrival in episode two could be an important turning point, particularly if Oya’s ambitions bring her directly into the complicated affairs surrounding Cemre and the rival families. For viewers looking for a new Turkish drama with mystery, romance and high-stakes family tension, Mercan Köşk is certainly one to watch as the new season begins.
