Skagiopoulio is the name of this big park and the surrounding neighborhood.
It was founded in 1926 together with an orphanage center for the aid of orphans from the wars located within the park. It is named after Panagiotis Skagiopoulos. The name is still used into the present day.
Nowadays called "Skagiopoulio Center for Boys of Patra", the old orphanage has been completely separated from the rest of the park, which is open for everyone. Next to it there are two basketball courts where a local team trains.
As a kid I lived close to the park and visited on a weekly basis. While in the 90s it was on pristine condition, and employed gardeners, guards and other personnel, nowadays it has been heavily neglected and left to decay. A small cafe opened on the early 00s (replaced a super small self service food truck style one that existed before, illegaly using a big part of the park). Thankfully it's the only thing keeping the park alive and open to the public. It's cheap and peaceful, and a good place to grab a cup of coffee.
Supposedly the park is open from dusk to dawn, but some doors are broken and left open 24/7. Still, I wouldn't recommend going in at night. It's not illuminated at all and perhaps there are people you would prefer to avoid. I strongly suggest going in through the "T0" waypoint.
The "Patras City" series is meant to showcase mainly urban areas of Patras. Those typically involve getting around the horrible city traffic, and on some cases total lack of parking spaces. This one usually has free parking spots around, and you can avoid the city center traffic, but still it might not be friendly for big campervans or people not familiar with Balkan city driving.
We ran out of sunlight the day we hid the cache, so there are no photos for now, other than a bad flash spoiler photo. I will add proper photos soon.
