Photograph of Hill County Courthouse in Hillsboro, TX]. The three-story white stone building sits on a green lawn filled with a few dark green bushes and trees along with parking meters, which line the sidewalk surrounding the courthouse. In the left side of the photo, a sign saying "See you in church Sunday" sits in the lawn. The widest side of the courthouse faces the right edge of the photo, though a large tree blocks its details from view. Each corner of the building resembles a tower as they sit out from the rest of the building a short distance, their grey sloping roofs ending in flat tops with small windows in the sides. Three rows of windows span the width of the courthouse's walls, appearing in pairs throughout most of the building. In the center of both of the visible sides of the courthouse are grey, triangular roofs held up by tall columns. A white clocktower sits in the center of the courthouse's roof. It has a sloping, windowed base supporting a straighter section with windows which is topped by the final section with the clockfaces. A weathervane rises from the top of the clocktower.
