Ask a local where to watch the sun go down and they'll point uphill to the Trigonion Tower. It's a squat Ottoman artillery bastion at the top corner of the Byzantine walls — but nobody climbs up for the tower. They come for what's below it: the whole of Thessaloniki tipping down to the Thermaic Gulf, red roofs to blue water, with Mount Olympus floating on the far shore. It's free, always open, and the single best view in the city. Here's the tower and how to make the most of it.
The quick version
There's nothing to pay and nothing to book — you walk up to the terrace beside the tower and the city does the rest.

It sits at the top of Ano Poli, where the Byzantine walls turn the corner of the hill, a short walk from the Heptapyrgion fortress.
A tower built for cannon
The Trigonion is younger than the walls it anchors. After the Ottomans took Thessaloniki in the 15th century they reinforced the corners of the old Byzantine circuit for gunpowder artillery, and this massive round tower went up in the late 1400s to mount cannon over the northeastern approach. Its other name, the Chain Tower (Zincirli Kule), points back to that defensive role. Today it's a solid, plain-faced bastion — handsome enough, but the reason it's on every itinerary is the terrace beside it, not the stonework.
The view
This is the most photographed panorama in Thessaloniki, and it earns it. From the terrace the city falls away in a sweep of terracotta roofs and white apartment blocks to the curve of the waterfront; the Byzantine walls run downhill in the foreground; and beyond the rooftops the Thermaic Gulf opens out, with cargo ships at anchor and Mount Olympus on the horizon on a clear day. It's the one spot that puts the whole shape of the city — hill, walls, sea — into a single frame.
Best time to visit
Come for sunset. The terrace faces roughly west and southwest over the gulf, so the light drops straight down the view and sets the roofs and water glowing — join the locals who bring a drink and settle on the grass. It's the headline stop in our best sunset spots guide. Mornings are quiet and clear for photos; midday is fine but flatter. Whenever you go, pair it with a wander through the Ano Poli lanes and a walk along the walls — the tower is the natural high point of that route, and it anchors the upper-town afternoon in our 2-day itinerary.
Getting there
The Trigonion crowns the hill above the old town, so reaching it means a climb — the fun way is on foot up through the stepped lanes of Ano Poli, which is half the experience. If the gradient isn't for you, a city bus toward the upper town or a cheap taxi drops you near the top, and you can walk down through the old quarter afterwards.
