Source-derived summary

The Lighthouse on Turtle Rock is a lighthouse built in 1887 to aid traffic on the Schuylkill River near Philadelphia, Pennsylvania. The lighthouse was constructed by Frank Thurwanger at a cost of $2,663 on an area of land just west of Boathouse Row. The lighthouse has a hexagonal lantern room with an octagonal walkway. Gas was first used to power the light, but in 1990, when the lighthouse was repainted and received a new wooden balustrade and newel posts, the beacon was electrified.

Sedgeley Club

The lighthouse is operated by the Sedgeley Club, a social club located at #15 Boathouse Row in the historic Boathouse Row along the Schuylkill River, which is listed on the National Register of Historic Places and designated a National Historic Landmark. In 1897, the club was founded as the Bicycle,

Barge and Canoe Club, but quickly changed its name to the Sedgeley Club. The Club initially occupied #14 Boathouse Row, until 1902, when the Fairmount Park Commission permitted the Club to build its own boathouse. The building, designed by Arthur H. Brockie, was adapted to encompass the lighthouse that predates it. Brockie designed a shingle, Colonial Revival house.

After completing this design, Brockie joined the University Barge Club in 1902.

The current lead gives the account dated anchors—1887, 1990, 1897, 1902—that can be checked directly. The linked authority record independently contributes the date 1887. For this dossier, Turtle, Rock and Light is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “lighthouse in Pennsylvania, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q7856452. Authority coordinates are 39.970, -75.190. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1887, 1990, 1897 and 1902.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
