Pererria is a Territory of the Empire of Adammia, surrounded by the West Midlands in the United Kingdom. It is made up of a section of quayside and the adjoining canal. It is most notable for being home to the headquarters of the Adammic Navy, Pererria Naval Base. It is 341m² in size. Its governor is Lady Admiral Madam Emily Simpson.
Pererria was originally located in Poole Harbour, but was forced to move in January 2018 after the bar adjoining the territory, which was previously owned by relatives of Admiral Simpson, was sold to persons unknown. It was then briefly located near to Simpson's term-time workplace in Birmingham city centre, but was forced to move again after she quit that job. It is currently located on the Worcester and Birmingham Canal, directly adjacent to University Station; it lies around 100 metres away from the University of Birmingham's School of Computer Science, where the Emperor of Adammia currently studies. Alongside Sandal Castle, it is one of the only Adammic territories whose exact location has been disclosed to the general public. It lies around a mile down the canal from the Wazakhstani city of Waztana, which can be accessed via the towpath; this makes it the closest point in Adammia to another micronation.
