Jacksonville is Florida's largest city by area at 874 square miles, but its two main historic sites are free and require no more than a day to cover. Kingsley Plantation 30 miles northeast is the oldest plantation house in Florida, with 25 tabby-shell slave quarters that stand as the most complete surviving set in the US. Downtown's Basilica of the Immaculate Conception, three blocks from the St. Johns River, dates to the first year of American territorial rule in 1821.

History
Kingsley Plantation Must-see
Duval County · Jacksonville
Kingsley Plantation is the oldest surviving plantation house in Florida, built in 1798 on Fort George Island at the mouth of the St. Johns River. Zephaniah Kingsley acquired the property in 1817 and ran it as a working cotton, citrus, and sugarcane plantation using enslaved labor until 1839. His wife, Anna Madgigine Jai, was a formerly enslaved Wolof woman from Senegal whom Kingsley freed and married in a ceremony in Cuba in 1806 — she managed the plantation operations and later owned her own property. Twenty-five tabby-shell slave quarters survive on the property, built in a distinctive curved line facing the river; this is the most complete set of plantation slave quarters remaining in the United States.
The plantation is part of the Timucuan Ecological and Historic Preserve, managed by the National Park Service. Admission is free. The main house, kitchen house, and barn are open for self-guided tours daily 9am to 5pm. The quickest route from downtown Jacksonville (30 miles) is via the Mayport Ferry across the St. Johns River — $8 per vehicle, departs every 30 minutes from Mayport Village — then north on A1A. Rangers are on-site weekdays and most weekends to answer questions about the site's complicated history.

Basilica of the Immaculate Conception (Jacksonville) Must-see
Duval County · Jacksonville
The Basilica of the Immaculate Conception at 121 E Duval Street is the oldest Catholic church in Jacksonville, with a parish established in 1821 — the year Florida was ceded to the United States from Spain. The current Gothic Revival structure was consecrated in 1878, rebuilt after the Great Jacksonville Fire of 1901 destroyed much of downtown, and elevated to the rank of minor basilica by Pope John Paul II in 1991. The exterior features twin spires visible from Hemming Park one block west, and the interior has European stained glass windows and a hand-carved wooden altar.
Admission is free and the basilica is open to visitors daily. Daily Mass is held at 7am and 12:10pm Monday through Saturday, and at 7:30am, 9:30am, and 11:30am on Sundays. The church is in the heart of downtown Jacksonville, two blocks from the Duval County Courthouse and three blocks from the St. Johns River waterfront. Hemming Park, Jacksonville's central public square, is directly across the street.
Planning Notes
Where to stay: Downtown Jacksonville hotels along the St. Johns River are within walking distance of the Basilica and the Riverwalk. For Kingsley Plantation, staying in the Beaches area (Atlantic Beach or Neptune Beach, 25 miles east) puts you closer to Fort George Island and the Mayport Ferry terminal, but adds distance from downtown.
Book ahead: Both Kingsley Plantation and the Basilica are free and require no advance booking. The Mayport Ferry operates every 30 minutes 6am to 10pm daily — no reservations needed. Call the Kingsley Plantation ranger station (904-251-3537) to confirm ranger-led tour times if you want a guided visit rather than self-guided.
Getting around: A car is required for Kingsley Plantation — it is 30 miles northeast of downtown via Heckscher Drive or the Mayport Ferry. The Basilica is in the walkable downtown core near Hemming Park. Plan a morning at Kingsley Plantation (allow 2 hours on site) and the Basilica as a downtown afternoon stop on the same day.
