F. _Grace Church._ This church, in York-Hampton Parish, is the oldest in Yorktown. It has been active since its construction about 1697. The present structure incorporated much of the original native marl walls. This church was used for various military purposes in the two wars that engulfed Yorktown, but parish organization has continued unbroken and services are held regularly. In its churchyard lie the remains of prominent men of Yorktown and of many others less well known. The church is normally open every day.

H. _York County Courthouse._ This structure, the fifth such to stand on Lot 24 in Yorktown, was completed in 1955. Although not a reconstruction, it does capture some of the architectural flavor of the time. It serves the town and county, as buildings on the lot have done since 1697. [Illustration: _The Sessions House._] I. _Swan Tavern Group._ This group of reconstructed buildings, including the tavern, kitchen, stable, smokehouse, and privy, all stand on original foundations. One of the characteristics of colonial Yorktown was the large number of its inns and taverns. The Swan, opened for business in 1722, was the most noted of all. J. “_Customhouse._” Directly across the street from the Digges House, this structure appears to have been built prior to 1733 and to have begun its history as Richard Ambler’s “large brick storehouse.” It has been acquired and restored by the Comte de Grasse Chapter, Daughters of the American Revolution, and now serves them as a chapter house. The building, on occasion, is open to visitors. K. _Edmund Smith House._ This brick residence is south of the Nelson House and faces Nelson Street. It dates from about 1730. L. _Ballard House._ Also located on Nelson Street, this cottage, sometimes called “Pearl Hall,” presumably was built by John Ballard. M. _Sessions House._ This house is the oldest building still standing in Yorktown. It was built in the late 17th century, and is named for its builder and first owner—Thomas Sessions. Many of the houses mentioned here are private homes which are sometimes open during Garden Week and other special occasions. These old homes add charm to Yorktown and do much to preserve a quiet dignity along the narrow, shaded streets far removed from the busy thoroughfares of a 20th-century town. For those interested in geology, mention should be made of the famous _Yorktown Cliffs_, particularly those in the area between Yorktown and the Moore House. In the steep banks eroded by the river, extensive and significant deposits of seashells are visible. These are of marine life that existed in the Miocene Epoch of the Tertiary Period millions of years ago. _How to Reach Yorktown_
