The pericardial cavity. Try the chest, or thoracic cavity.
Cranial cavity - serous membranes dorsal cavity = the back ventral cavity - has the thoracic cavity which contains the lungs(parietal pleura and visceral pleura membranes) and the heart (parietal pericardium and visceral pericardium membranes), the abdominal cavity (parietal peritoneum and visceral peritoneum membranes) and the pelvic cavity which is also peritoneum membranes)
The space between the epicardium and the parietal pericardium is called the pericardial cavity. This cavity contains a small amount of pericardial fluid that acts as a lubricant to reduce friction between the membranes during heart contractions.
The heart as well as the sections of the heart such as the Left and Right Pulmonary Arteries, the Left and Right Pulmonary Veins, the Superior Vena Cava, and the Thymus gland.
The serous pericardium is a thin, double-layered membrane that covers the heart and consists of the parietal pericardium (outer layer) and visceral pericardium or epicardium (inner layer). The fibrous pericardium is a tough, fibrous layer that surrounds the serous pericardium and helps protect the heart and anchor it within the chest cavity.
The outermost layer of the pericardial membrane is the fibrous pericardium. It is a tough, protective layer that surrounds the heart and helps anchor it in place within the chest cavity.

Since the parietal pericardium is right outside the Pericardial cavity, then I believe you can simply say the parietal pericardium itself is located in the mediastinum in the thoracic cavity.

pericardial cavity
There is no such thing as the pericardial cavity. The visceral pericardium is the outer layer of the heart, and also called the epicardium. The lining on the inside of the pericardium is called the parietal pericardium.
The pericardium is the fluid filled sac that surrounds the heart, aorta, vena cava, and the pulmonary artery. The pericardium keeps the heart in the chest cavity.
The pericardial cavity is located in the thoracic region of the body, specifically between the two layers of the pericardium that surround the heart. It is situated in the mediastinum, which is the central compartment of the thoracic cavity.
Thoracic cavity is the place where the heart is covered by pericardium membrane
