Castelo de Sao Jorge Archaeological Site - Iron Age Lisbon

Explore the archaeological excavations at Lisbon's iconic hilltop castle, where Iron Age occupation from the 8th-6th centuries BC has been confirmed. The site reveals Phoenician pottery, Mediterranean architectural influences, and in 2010 archaeologists discovered a 7th-century BC stele with Phoenician inscriptions - the oldest such lapidary find in the Iberian Peninsula.

What to do there

5 things to do

1. 1 Find the Layer That Rewrote Iberian History History · Free

   The Praça Nova archaeological pit — 2,700 years of occupation visible in a single cross-section

   In 1996, archaeologists started digging in Praça Nova and could not stop. Three distinct civilisations appear as literal layers: Iron Age settlement (7th century BC) where Phoenician traders lived alongside local Lusitanians at bottom, Moorish residential neighbourhood (11th century) with complete streets and houses in middle, 15th-century Bishops' palace destroyed in 1755 earthquake on top. You're looking at 2,700 years of unbroken human occupation in a hole in the ground, making Lisbon one of Europe's most continuously occupied sites. Walk through the main gate to the eastern square past the main courtyard — contemporary white/steel structures hover over the open excavation pit. Lean over the railing and identify the three colour-bands in the soil: the darker the layer, the older it is.

   Backup: If the excavation is temporarily covered for conservation, interpretive panels around the perimeter show high-resolution cross-sections of what's below. The Cistern Room has the actual artefacts.

2. 2 Hold a Phoenician Wine Amphora in Your Mind Wine · Free

   The Cistern Room — where 2,700-year-old wine trade objects sit under your nose

   You're about to see physical evidence of the Phoenician wine trade in Lisbon. Archaeologists found 30 ceramic sherds during Praça Nova excavations — amphorae, red slip wares, grey wares, cooking pots from Greece, the Near East, and North African coast, brought by Phoenician traders sailing up the Tagus from Cádiz and Huelva. The 7th-century BC Phoenicians living on this hill were wine merchants, the same people who planted Moscatel grape across the river in Setúbal. In the Sala da Cisterna (underground museum, follow signs to 'Museu'), look for amphora fragments — tall, narrow-necked, with pointed bases designed to wedge into ship cargo. Ask the attendant: 'Qual é o objeto mais antigo aqui?' The answer involves the Iron Age Phoenician contact period.

   Backup: Display cases are labelled Portuguese and English. If at capacity (rare), wait five minutes. Labels reference 'Período da Idade do Ferro' — Iron Age, your target layer.

3. 3 Stand Where Iron Age Sentinels Watched for Phoenician Ships Adventure · Free

   The southern ramparts — the exact vantage point from which the original inhabitants scanned the Tagus

   In the 7th century BC, people living on this hill would have scanned this exact view daily for Phoenician ships coming from southwest: rounding Cape St. Vincent, entering the Tagus estuary, rowing upstream toward this hill chosen for strategic control over all river traffic. From Praça Nova, walk to southern ramparts facing the river until you reach the section with clearest southward view. Look southeast across the water — that landmass is Setúbal Peninsula where Phoenician traders planted Muscat of Alexandria vines. Those same vines, 2,700 years later, still produce Moscatel de Setúbal you can buy in any supermarket. The Phoenicians didn't just trade here; they changed what grows in this soil permanently, and on clear days you can literally see their legacy.

   Backup: If visibility is poor, the castle map (free with ticket) marks the southern rampart as best Tagus viewpoint. Any section of the southern wall works — the view is consistent along 200 metres.

4. 4 Watch Lisbon Move in a Camera Built for a King Adventure · Free

   The Tower of Ulysses camera obscura — the city projected live onto a circular bowl, every 20 minutes

   Inside the Tower of Ulysses, a system of lenses and mirrors projects a live 360-degree view of Lisbon onto a circular concave bowl — you watch ferries crossing the Tagus, tourists on Alfama rooftops, cloud shadows moving across hilltops in real time, like watching the city from above without glass between you and the image. The device was built as scientific curiosity and navigational aid for observing city and port in safety. The tower (tallest in the castle complex, signposted from main courtyard) runs demonstrations every 20 minutes; last session 3 PM. Arrive 5 minutes before a demo, stand quietly in the dark, and when the image appears look for the Tagus and southern bank — you're watching the same river Phoenician ships sailed 2,700 years ago, rendered live, on top of the hill they chose to trade on.

   Backup: If camera obscura is closed (bad weather, maintenance), climb the tower exterior stairs for 360-degree live view from battlements — no projection, but same sightlines unobstructed.

5. 5 Drink the Grape the Phoenicians Left Behind Wine · Price: low

   SEM wine bar in Alfama — natural Portuguese wine 15 minutes downhill from the castle, in a wine tradition that started on this hill

   Order a glass of Moscatel de Setúbal at SEM Restaurant & Wine Bar (R. das Escolas Gerais 120, Alfama, 15 minutes downhill from castle gate via Rua de Santa Cruz do Castelo). The grape — Muscat of Alexandria, called 'the Phoenician variety' in wine literature — was brought to Setúbal Peninsula (visible from the castle rampart you just stood on) by Phoenician traders around 8th-7th century BC. The same people whose pottery sits in the Cistern Room planted this grape across the river, and it's still producing wine after 2,700 years of continuous agriculture. When the glass arrives, tell whoever you're with: 'This grape was planted by the people whose city we just walked through.' SEM's wine selection focuses on small producers using natural methods closest to ancient winemaking philosophy.

   Backup: If SEM is full, walk five minutes to A Muralha Tasca Típica near the Fado Museum — same neighbourhood, same local wine focus. Any Moscatel de Setúbal in any Alfama wine bar completes this step.
