Alicante Sightseeing: Castle to Cota Cero
Every topographic height printed on a Spanish map traces back to a brass plaque on the floor of Alicante’s City Hall, which is a strange thing to learn standing in a municipal foyer that most visitors walk straight past.
Castillo de Santa Bárbara
The fortress crowning Mount Benacantil at 166 meters is free to enter, walls, ramparts and exhibition rooms included; only the tunnel elevator from opposite Postiguet Beach costs anything, at €2.70 a ride. Inside, the 16th-century Hall of Philip II and the upper keep’s 360-degree views are the reason to make the climb, on foot through Barrio de Santa Cruz or by lift. A guided castle and old town tour is worth the cost if you want the history explained rather than read off a plaque as you go. Full hours and seasonal closures are listed on the official castle site ; it stays open until 23:00 in summer and closes on December 24, 25 and 31 and January 1 and 6.
Explanada de España
This palm-lined seafront promenade is paved with 6.6 million tricolor marble tiles laid in an undulating wave pattern, running from Puerta del Mar to Canalejas Park under four rows of Canary Island date palms. It costs nothing and rewards an unhurried walk more than a quick photo stop.
Ayuntamiento and the Cota Cero
Alicante’s 18th-century City Hall, on Plaza del Ayuntamiento, holds a detail most guidebooks skip: a bronze marker at the foot of the main staircase, established in 1874 after four years of tidal measurement in the port, that still defines mean sea level for the whole of mainland Spain. Every elevation figure on a Spanish topographic map traces back to this one plaque.
Concatedral de San Nicolás
Built between 1616 and 1662 over the remains of a former mosque, this co-cathedral’s austere Herrerian exterior gives way to a 45-meter blue cupola and a quiet 17th-century cloister. Entry is free outside services.
MARQ and MACA
MARQ , the Archaeological Museum, won European Museum of the Year in 2004 for its interactive scenography spanning prehistory through the Middle Ages. General admission is €6.00, reduced admission (students, seniors, large families) is €3.00, and Sundays and public holidays carry the same €3.00 reduced rate rather than a separate fee. A combined 30-day ticket covers MARQ plus three further archaeological sites, Lucentum, La Illeta dels Banyets and the Almudaina Tower, for €8.00 general or €6.00 reduced, four sites on one ticket. MACA , the contemporary art museum inside the 17th-century Casa de la Asegurada, is free and holds original Picasso, Miró and Dalí pieces donated by kinetic artist Eusebio Sempere.
A guided walking tour of Alicante’s landmarks strings the castle, the Explanada and the old town together in one morning for travelers who would rather not plan the route themselves. Both museums close Mondays, so build a sightseeing day around Tuesday through Saturday if MARQ and MACA are on the list. For where to eat between stops, our solo activities guide covers the market and tapas scene in more detail.
