For thousands of years, a small hill on the outskirts of Aberdeen has hidden away pieces of its archaeological past.
From Bronze Age burial cairns to huts from a WWII Prisoner of War camp, Tullos Hill's colourful and archaeologically significant history has made the grassy mound one of Aberdeen's most interesting attractions.
Sandwiched between Tullos and Altens industrial estates, human activity on the site can be traced back as far as the Mesolithic period.
A collection of seashells discovered with food remains and organic rubbish on the Bay of Nigg shoreline suggested hunters and gatherers built a seasonal camp there, around 8000 to 6000 BC,
Racing the clock forwards, a collection of cairns dotted around the hill reveal the area's Bronze Age connections. The cairns managed to survived thanks to protective overgrown gorse, even though the hill became a rubbish tip for modern day Aberdeen in the 60s and 70s.
Chris Croly is keen for others to learn about this self-preserving mound and its historical importance in the area.
"Nowadays there is the need to carry on protecting what is there [at Tullos Hill] and part and parcel of that is to keep the hill very visible," he explained.
A project officer in public engagement with research at the University of Aberdeen, Chris will explore Tullos Hill’s colourful past in a quickfire presentation known as PechaKucha at the Belmont Filmhouse on Tuesday.
Translated as chitchat in Japanese, the PechaKucha talks will give participants just 20 seconds to describe each of their 20 slides, with the presentation and conversation tool offering a host of speakers from the University of Aberdeen the opportunity to address topics from climate change to equal rights based on the theme of One World Week.
Chris explained: "Tullos Hill fits in quite well with the One World theme in a number of respects through environmental issues and a number of nations.
"Known as part of the Gramps, despite being a landfill site for 30 years as well as encroachment from Altens and Tullos industrial estates, its natural response has helped to retain its archaeological importance.
"Given recent work to curb the landfill, we were able to investigate a lot more and find what had survived."
Although the hill was already known to be a place of burial during the Bronze Age, a survey commissioned by Aberdeen City Council in 2004 helped to identify 120 previously unknown archaeological features from prehistoric field boundaries, hut bases from the WWII Anti Aircraft Battery and Peterseat Prisoner of War camp from 1945.
Chris said: "There were a lot of young German guys [at the Prisoner of War camp] and while they took roll call, it was a fairly loose affair, playing football with local teams and many stayed on and married into local families. A lot were drafted in to build what is Tillydrone housing estate.

"One man who stayed Karl Ludwig Roth got in touch when the Art Gallery and Museums was investigating and donated pictures from his time during the camp."
Chris’ quickfire presentation will showcase Tullos Hill from throughout the ages, with the aim of educating and inspiring others to become interested in the site so as to protect it for generations to come.
He added: "It’s a unique site and it has so much to offer with the historic landscape that is has survived."
PechaKucha takes place on Tuesday from 7pm at the Belmont Filmhouse and is free for all to attend
