O’Callaghan Collection is a group of four luxurious boutique hotels, located in a premier setting at the heart of Georgian Dublin. With a total of 413 guestrooms and meeting space for up to 200 delegates, the collection offers the perfect blend of comfort, style, and convenience for both leisure and business travellers.

Each hotel has its own unique personality—think of them as siblings in the same family:

• The Davenport – Refined, luxurious, traditional, classy.
• The Alex – Stylish, clever, comfortable, design-led.
• The Green – Sophisticated, feminine, contemporary, fashionable.
• The Mont – Fun, cheeky, sociable, cool.

Three of the four hotels—The Alex, The Davenport, and The Mont—are uniquely positioned on the same square, just 30 seconds apart. This rare setup allows for a seamless group experience: meet at The Alex, dine at The Davenport, and host an exclusive event at The Mont—all coordinated by a single dedicated contact on our events team.

The Alex is home to the collection’s largest event space. The Orient can accommodate up to 200 delegates in a cabaret setup or be partitioned into four flexible spaces. Two additional rooms—Odyssey and Rovos—are ideal for smaller gatherings or as breakout rooms, making the venue perfectly suited for a range of event styles.

With distinct personalities, shared service excellence, and an unbeatable central location, O’Callaghan Collection offers a truly unique and memorable experience in Dublin.
