Gallagher Headquarters Ranch is a world all unto itself. An incredibly peaceful and protected setting so close to a metropolitan area. It’s like going back in time both in the natural world as well as the historical buildings as if time stopped in the mid 1800’s when the ranch was founded by Peter Gallagher, an Irish immigrant, brought to San Antonio as a young engineer-master stone mason by Santa Anna.   Today with all the modern amenities of a new home this hand cut stone 19 bedroom, 17 and ½ bath historic compound with 22 original fireplaces, sprawling porches, huge manicured lawns and beautiful gardens makes it seem that you are on a working historic Spanish hacienda.

The Ranch has been a gathering place for the owners and their families for over 150 years.  Its headquarters overlooks the clear flowing San Geronimo Creek from a gentle oak shaded rise.  This is Edwards Plateau or Texas Hill Country at its best with stunning live water, deep lakes, high mountains, lush trees, native flowers, and abundant wildlife all within a protected working ranch setting.

The Gallagher Headquarters Ranch has one Conservation Easement with The Nature Conservancy and two with the City of San Antonio Aquifer Protection Program.  These easements allow recreation, hunting, agriculture, and limited development.  The Headquarters Complex and the 35 acres surrounding the improvements has no conservation easements or restrictions allowing for expansion of infrastructure and improvements.  The Gallagher is divided into several districts; San Geronimo Creeks and Valleys, Conservation Hills, and Headquarters Complex.  Within these distinct areas one could focus on enhancing development, or further protecting the rich plants, water, and wildlife of the region.

San Geronimo Creeks and Valleys

 “Peter Gallagher topped arise twenty-odd miles from San Antonio de Bexar and saw spread out before him to the peaks of distant mountains behind which the sun was setting the lovely Valley of the San Geronimo River. Below him was the site he would select for Santa Anna’s supply base. Below him in this fertile valley with its deep canyons and rugged hills, he would claim

10,000 acres under a grant from the Mexican Government and establish what would become the historic Gallagher  –Dade Rayfield

This area comprises of all the San Geronimo Creek and Lakes frontage consisting of 741.881 acres.  The San Geronimo Creek flows through the Ranch for over one and a half miles.  This is a regional creek starting north of the property on very large ranches and runs south with the development of four rock and concrete dams along the way.  These dams vary in size and back up water into huge lakes or gentle meandering pools with limestone bluffs along the way.  They have been established since the 1850’s and boast some of the largest bass populations in the Hill Country.  In the mid 1800’s Peter Gallagher undertook a large engineering project. He quarried massive limestone rocks from the surrounding hills to build an Acequia or Aqueduct. It resembles a roman ruin that once delivered water to the area from upstream dams for irrigation of lush fields.  The Creek is bounded on the east by the mountain country creating huge cliffs and bluffs and on the west by a beautiful valley with deep soils, huge trees, and a wonderful diversity of Hill Country plants and wildlife.

Conservation Hills

There is a 731 ac conservation easement in the high mountains east of the headquarters that allows limited development while protecting the rare plants and animals in a partnership with The Nature Conservancy.  These beautiful tree covered hills have a great road system for hiking, mountain biking, horseback riding, or just cruising in a jeep in a wooded wonderland.  Adjacent to the Ranch and across the highway is a huge 11,576 ac State Natural Area called Government Canyon, one of the largest urban parks in the country.  In all, the conservation values of this land are unequaled, and the amazing habitat is home to a wide diversity of songbirds, game, and all kinds of native plants and animals.  Spring migration of neo-tropical birds are stunning including the vermillion flycatcher, painted bunting, golden cheeked warbler, hummingbirds, and many more.

Headquarters Complex

The Headquarters are a complex of main rock buildings, barns, corrals, outbuildings, and staff quarters.  Peter Gallagher built the original fortress house in the 1830’s which over the past 150 years grew into a sprawling complex, constructed of matched limestone blocks quarried from the ranch, meticulously restored by the current owner.  The complex is the hub of the ranch with its houses, barns, outbuilding, gardens, lawns, and its many outdoor entertainment areas, perfect for the enjoyment of the owners’ guests and housing for the ranch employees.

A small dirt tank surrounds a seep providing water for wildlife.  San Geronimo provides additional year round water through the heart of the ranch.
