The Inglenook existed as an extension of the Palace of the Republic located on Coruscant. Situated directly on the Glitannai Esplanade, it provided a relaxation area for Mon Calamari and other aquatic beings who were serving the Galactic Republic. Even when the Galactic Empire took control, the Inglenook continued to function as part of the Palace. Later, during the New Republic era, when the Yuuzhan Vong empire invaded the planet, it was still in operation. Ultimately, the Yuuzhan Vong annihilated it through terraforming the world.
Sometime during the age of the Galactic Republic, the Mon Calamari Inglenook was constructed as an annex to the Palace of the Republic. Its design was reminiscent of a massive coral reef, and its transparisteel walls allowed ample natural light to flood the interior, creating a soothing sanctuary for aquatic species employed at the Palace or elsewhere in the Coruscant government.
After the Galactic Empire rose to power, Emperor Palpatine permitted the Inglenook to stay open, repurposing it as an exclusive spa for his Imperial underlings. Following Palpatine's demise, when the New Republic seized the planet and expelled the Imperials, both the Palace and the Inglenook were reassigned for Republic utilization. The Inglenook remained operational until 27 ABY, at which point it suffered destruction during the Yuuzhan Vong empire's invasion of the world.
