The chapel most people call the Alamo started life in 1718 as Mission San Antonio de Valero, the first of five Spanish missions strung along the river. The same year gave the city its founding. The missions came first, the 1836 battle made one of them famous, and three centuries of Spanish, Mexican, and Texan history have been layering up along that river ever since. Four of those missions still stand together as a UNESCO World Heritage Site.
I spent a career teaching history before joining my sons at More Than Just Parks, and few American cities wear their history as openly as this one, where the River Walk winds below street level and the past is never far from the surface. These are the 10 San Antonio landmarks I would send you to, counted down from number 10.

10. San Antonio Zoo
The San Antonio Zoo, set in the limestone quarry and along the headwaters of the San Antonio River in Brackenridge Park, is one of the most-visited zoos in the country, home to thousands of animals.
Founded in 1914, the zoo grew within an old rock quarry, which gives some exhibits their dramatic cliff backdrops. It holds animals from around the world across habitats for big cats, primates, birds, and an aquarium, and it has long been recognized for its work breeding rare and endangered species, including whooping cranes and Caribbean flamingos. A children’s zoo, a train, and a carousel make it a favorite family outing.
9. Briscoe Western Art Museum
The Briscoe Western Art Museum, in a restored 1930s library building on the River Walk, celebrates the art, history, and culture of the American West.
Opened in 2013 and named for former Texas governor Dolph Briscoe and his wife Janey, the museum holds Western paintings, sculpture, and artifacts, including a saddle owned by Pancho Villa and a Wells Fargo stagecoach. Its galleries trace cowboys, vaqueros, Native nations, and the frontier story, and the riverside sculpture garden makes it one of the most pleasant stops on the River Walk.
8. San Antonio Botanical Garden
The San Antonio Botanical Garden spreads across 38 acres just northeast of downtown, a living showcase of Texas plant life from Hill Country to desert, plus a striking glass conservatory.
The garden opened in 1980. Its centerpiece is the Lucile Halsell Conservatory, a cluster of dramatic glass towers designed by architect Emilio Ambasz that sink partly underground to shelter tropical and desert collections from the Texas heat. A native Texas section recreates the state’s varied landscapes, and the WaterSaver Garden shows off drought-tolerant plants. Seasonal exhibits and a family adventure garden round out the visit.
7. Natural Bridge Caverns
Natural Bridge Caverns, just north of San Antonio, is the largest commercial cave system in Texas, a world of active stalactites and stalagmites discovered by college students in 1960.
The caverns take their name from the 60-foot limestone bridge at the entrance. Four St. Mary’s University students explored the cave in 1960, and it opened to the public in 1964. Guided tours descend past towering formations still slowly growing drop by drop, and the site has added zip lines, a maze, and a gem-mining attraction above ground. It is a designated U.S. Natural Landmark.
6. San Fernando Cathedral
San Fernando Cathedral on Main Plaza is the oldest standing church building in Texas and one of the oldest cathedrals in the United States, the spiritual heart of San Antonio for nearly three centuries.
Canary Island settlers and Spanish colonists built the original church between 1738 and 1750, and its walls form part of today’s cathedral. During the 1836 siege of the Alamo, General Santa Anna is said to have raised a blood-red “no quarter” flag from the church, then the tallest structure in town, signaling that no defenders would be spared. A marble coffin inside the cathedral is said to hold remains of Alamo defenders, recovered in 1936. Today a nightly light-and-sound show projected on the facade draws crowds to Main Plaza.
5. Spanish Governor’s Palace
The Spanish Governor’s Palace, a low whitewashed adobe near Main Plaza, is the only surviving example in Texas of an aristocratic Spanish colonial townhouse. It is a National Historic Landmark.
Built in the 1700s, the building served as the home and offices of the captain of the local Spanish presidio, the military garrison that guarded the settlement, rather than a true governor’s residence. Its keystone over the entrance still bears the Spanish royal coat of arms and the date 1749. The city bought and restored it in the 1920s, and visitors can walk its period rooms and the tranquil cobblestone courtyard. It is a rare, tangible link to San Antonio’s Spanish colonial founding.
4. Tower of the Americas
The Tower of the Americas rises 750 feet over downtown, the landmark left behind by the 1968 World’s Fair and one of the tallest observation towers in the country.
Built as the centerpiece of HemisFair ’68, the world’s fair that marked San Antonio’s 250th anniversary, the tower was designed by local architect O’Neil Ford. An elevator climbs to an observation deck and a revolving restaurant with views across the city to the Hill Country. The surrounding HemisFair park has been reimagined with playgrounds and gardens, but the tower remains the city’s most recognizable piece of the modern skyline.
Top 3 San Antonio Landmarks
3. San Antonio Missions National Historical Park
San Antonio Missions National Historical Park preserves four of the five Spanish colonial missions strung along the San Antonio River south of downtown. With the Alamo, these missions form Texas’s only UNESCO World Heritage Site.
The park protects Missions Concepción, San José, San Juan, and Espada, founded by Franciscan priests in the 1700s to convert and settle the region’s Native peoples under Spanish rule, a system that brought Christianity and European agriculture but also disease and the loss of Indigenous ways of life. Mission San José, the “Queen of the Missions,” is the largest and best restored, with its famous Rose Window. Several remain active parishes. The park was established in 1978, and in 2015 the four missions and the Alamo were jointly inscribed as a UNESCO World Heritage Site. A riverside trail links the missions for walkers and cyclists.
2. San Antonio River Walk
The San Antonio River Walk is the city’s beloved network of stone paths winding a story below the streets along the San Antonio River, lined with restaurants, cafes, and shaded by cypress trees. It is one of the most popular attractions in Texas.
The River Walk grew out of a flood-control plan after a deadly 1921 flood. Rather than pave over the river, the city, with a design by architect Robert Hugman and labor from Depression-era federal work programs, turned the downtown bend into a landscaped promenade in the late 1930s. It blossomed around the 1968 World’s Fair and has since been extended for miles, linking downtown to the missions and the Pearl district. River barges glide beneath stone bridges, and each holiday season the banks light up for the crowds.
1. The Alamo
Our number one San Antonio landmark is the Alamo, the former Spanish mission whose 1836 siege became the most famous chapter in Texas history. “Remember the Alamo” still echoes far beyond Texas.
The site began in 1718 as Mission San Antonio de Valero, one of the first Spanish missions in the area, and later became a military post nicknamed the Alamo. During the Texas Revolution against Mexico, a small force of Texian and Tejano defenders held the compound for 13 days in early 1836 against the much larger army of General Antonio López de Santa Anna. All of the defenders, among them James Bowie and Davy Crockett, were killed when the Alamo fell on March 6, 1836. The loss became a rallying cry, and weeks later Texan forces won independence at the Battle of San Jacinto. Owned by the State of Texas, the Alamo joined the four mission-park churches as a UNESCO World Heritage Site in 2015. Admission to the historic chapel is free.

You should know that this guide does not come out of thin air. More Than Just Parks is a family operation. My sons Will and Jim have spent their adult lives exploring and filming America’s national parks and public lands destinations, working with the National Park Service, the Department of the Interior, the USDA, and the U.S. Forest Service along the way. In 2018, after a career teaching history, I joined them to help tell the stories behind these places.
