Portugal
LisbonLisbon carries its layers close together: a hilltop besieged in 1147, a royal square rebuilt after the 1755 earthquake, a secret police headquarters that fired its last shots in 1974, and industrial waterfront turned into a World's Fair in 1998. Moors, kings, dictators and engineers each left their mark on the same short walks.

4 records Portugal OeirasOeiras, on the Tagus estuary west of Lisbon, grew from a fishing and defensive coastline into a municipality in 1759 under the Marquês de Pombal, and later into a dense Lisbon suburb, its ground marked by a fort, a railway, and a science institute built without a chain of command. 1 dig
12 records Portugal Salvaterra de MagosSalvaterra de Magos grew around a royal hunting lodge built in the 1500s, favored by the Portuguese crown into the 1700s, where a marriage contract had already been signed in 1383. Fires in 1817 and 1828, then an 1858 earthquake, brought the palace down, leaving only its chapel and falconry standing. 1 dig
9 records Portugal PenichePeniche, on the Portuguese coast, is defined by its fortress: raised from 1557 against pirate raids, it later held foreign internees and prisoners of war before becoming, from 1934 to 1974, one of the Estado Novo dictatorship's most feared political prisons. 1 dig
8 records Portugal Sobral de Monte AgracoSobral de Monte Agraço is the hill town where André Masséna's invading French army was stopped in October 1810, held through a starving winter behind Wellington's Lines of Torres Vedras, and turned back towards Spain in March 1811, never reaching Lisbon. 1 dig
5 records Portugal MafraMafra grew around a king's vow: John V promised in 1711 to build a convent if his wife bore an heir, and that promise became the vast Palace of Mafra, finished in 1755. The town's old stone pillory still stands nearby, marking older judicial ground. 1 dig
12 records Portugal GrandolaGrândola, in the district that bears its name, is remembered above all for lending its name to a song. On 25 April 1974, 1 dig
4 records Portugal Santa Maria MaiorSanta Maria Maior, a parish in central Lisbon, holds ground once ruled by kings and monks alike. The Ribeira Palace stood here for around 250 years before the 1755 earthquake destroyed it, and Carmo Convent, founded in 1389, still stands roofless from that same morning. 2 digs
23 records
7 records Portugal AldoarAldoar, on the edge of Porto near the mouth of the Douro, holds ground where a bishop's Renaissance chapel was later swallowed by a fortress wall. Built in the 1520s and rebuilt into a bastion against Spain between 1646 and 1653, it marks a place shaped by faith and defence in turn. 1 dig
5 records Portugal MisericordiaMisericórdia is a Lisbon parish shaped twice by disaster — the 1755 earthquake and the 1988 Chiado fire — where a poet's uncertain grave, a ruined convent, and rebuilt shopping streets sit together around Praça Luís de Camões and Largo do Chiado. 2 digs

AlmadaAlmada, on the south bank opposite Lisbon, holds ground shaped as much by natural forces as by people. At Charneca de Caparica, a fossil sea cliff and a planted pine forest sit side by side, both eventually fenced off by law to keep the land from disappearing further.

Parque das NacoesParque das Nações occupies a stretch of Lisbon's Tagus riverfront that passed through shipbuilding, wartime seaplanes, transatlantic flying boats, and decades of slaughterhouses and refineries before the 1992-1998 clearance for Expo '98, which left behind the Vasco da Gama Tower and its sculpture Cursiva.
