While walking around Point Loma this weekend, I came upon another historical marker with a plaque that commemorates San Diego’s famous old La Playa Trail. This marker stands in front of a shopping center near the corner of Midway Drive and Rosecrans Street. It features one of six similar plaques created back in the 1930s.

You can see a photo of another such plaque at the east end of the La Playa Trail, near Mission San Diego de Alcala, by clicking here. You can see a third plaque at the base of Presidio Hill and learn about the remaining three plaques (which I have yet to photograph) here.

According to Wikipedia: “The La Playa Trail was a historic bayside trail in San Diego, connecting the settled inland areas to the commercial anchorage at Old La Playa on San Diego Bay…The trail was used during the Pre-Hispanic (Native American), Spanish, Mexican and American periods of San Diego history. Much of the length of the original trail corresponds to the current Rosecrans Street in the San Diego neighborhood of Point Loma…The trail was already established by the time the Spanish settlers arrived in 1769; the first inhabitants of the area, including the Kumeyaay tribe, used it to access the beaches of San Diego Bay. It was improved and extended during the Spanish colonization of the region, reaching Old Town San Diego and Mission San Diego de Alcalá in Mission Valley by the 1770s. Cargo which had been unloaded by ship at Ballast Point in Old La Playa was transported along the trail several miles inland to Old Town…”

Have you read the classic of American Literature, Two Years Before the Mast? It’s one of my all-time favorite books. Richard Henry Dana Jr. wrote an account of a sailor’s life on the coast of California in the mid-1830s, and a good portion of his fascinating narrative describes San Diego.

La Playa (then a beach on Point Loma just inside San Diego Bay) is where merchant ship Pilgrim unloaded cattle hides that had been gathered by Dana and his shipmates up and down the California coast. When Dana rode on horseback from the hide houses on the beach to Old Town, or farther east to Mission San Diego, he followed the La Playa Trail!

Historical markers at entrance to Presidio Park.

Several historical markers can be found near the northwest entrance to Presidio Park. If you’ve ever driven along Taylor Street just past Morena Boulevard and the Presidio Recreation Center, you might’ve glimpsed them. They stand beside a sidewalk that comes to an abrupt end, in a place where almost nobody walks.

The three markers were placed years ago near three sites of historical importance: the Serra Palm, Derby Dike, and the La Playa Trail.

I’ve transcribed the words on each plaque.

I was told by a park ranger who happened to be parked nearby that the Serra Palm is long gone. He said it was probably blown over in a windstorm, and pointed out a pine tree that was toppled by our most recent storms.

The Serra Palm was planted in 1769 by Padre Junípero Serra, and marked the beginning of El Camino Real.

I’ve photographed a similar La Playa Trail marker near Mission San Diego de Alcalá. To view that photo, click here.

According to Wikipedia: “In 1934, six commemorative terra cotta plaques were placed along the length of the trail by the local chapter of the Daughters of the American Revolution and other groups, based on a relief designed by sculptor Rose M. Hanks. The original six were located at Mission San Diego de Alcala; at the foot of Presidio Hill in Old Town; near the intersection of Rosecrans St. and Midway Blvd. in the Midway area; at the corner of Rosecrans and Lytton streets in Loma Portal, across from the Naval Training Center San Diego golf course; at the corner of Rosecrans and Byron streets in Roseville; and at the site of the fuel depot at Naval Base Point Loma…”

Founders Day is being celebrated in Old Town this weekend. The unique Old Town San Diego Chamber of Commerce event, which is inspired by our city’s 250th anniversary, is being held along San Diego Avenue, just south of the State Park.

I walked around at noontime today and took photos!

The colorful Founders Day festival will continue tomorrow. There will be street vendors and music and dancing and a whole lot of history to experience. If you can, head to Old Town San Diego and check it out!

A new flag is raised for San Diego’s 250th Anniversary!

This evening a very special event was held in San Diego.

A crowd gathered near the top of Presidio Hill, in the parking lot just below the Serra Museum, to take part in the San Diego 250 Civic Commemoration Ceremony.

The historic event was staged in the same spot overlooking San Diego Bay where a Spanish mission and presidio were built in 1769. It is where San Diego began 250 years ago.

The first part of the San Diego 250 Civic Commemoration Ceremony featured cultural entertainment representing our remarkably diverse city. Several colorful dances were followed by speeches by politicians, dignitaries and diplomats, plus several leaders of the Native American Kumeyaay people–those who have lived in this region many thousands of years before the arrival of Europeans. The audience experienced a Kumeyaay blessing and traditional Bird Songs. With sincere words past injustices and the suffering of the Kumeyaay were acknowledged, and optimism was expressed that our city’s future will be inclusive and bright.

For as long as I can remember, three flagpoles have stood at this place where the Spanish built their first outpost in California. Three banners have flown representing the history of San Diego: the flags of Spain, Mexico and the United States.

A fourth flagpole was recently installed. Today, at the close of the ceremony, a flag incorporating the different tribes of the Kumeyaay Nation was blessed with white sage smoke–to purify minds and hearts-and raised proudly, acknowledging and honoring San Diego’s first people.

I took some photographs of this important historical event.

Huge banner celebrates San Diego’s birthday!

The County Administration Building in downtown San Diego got a gigantic new banner today! It celebrates the 250th Anniversary of San Diego’s founding!

Those who look up at the banner from the Embarcadero are reminded that San Diego–which started very modestly back in 1769 with the construction of a Spanish mission and presidio–was California’s first port and first city!

Huge banner on sail of Star of India celebrates the 250th Anniversary of San Diego!

The City of San Diego has placed an enormous banner on a sail of the historic tall ship Star of India. Its bold message can be seen from many spots downtown. The banner celebrates San Diego’s 250th Anniversary!

In 1769, on the hill that overlooks what would eventually become Old Town, Spain began its settlement of the region by building El Presidio Reál de San Diego. Attached to the fort, the original Mission San Diego de Alcalá was established by Junípero Serra in the same year.

Back then the land was wide open and mostly wilderness. The mountains, hills, rivers and coast were home to the Native American Kumeyaay. European settlement brought about an abrupt change in the region’s history. For better or worse, 250 years later San Diego is quite a bit different!

What will San Diego look like in another 250 years? As our civilization evolves, and as technological breakthroughs accelerate, can anyone possibly imagine?

Together we sail into the future!

San Diego’s 250th Anniversary coming in 2019!

Close photo of bowed head of The Padre on Presidio Hill.

If one considers San Diego’s founding to have occurred in 1769, the year both Mission San Diego de Alcalá and the El Presidio Reál de San Diego were established on Presidio Hill, then 2019 will be our city’s 250th Anniversary!

That’s no small thing! One would suppose that huge celebrations are being planned!

Well, when I perform an internet search, I can find no plans for celebrations mentioned, apart from Mission Basilica San Diego de Alcalá’s announced church events, and a Founders’ Day Festival in Old Town.

It’s hard to believe, but I find almost no discussion of the city’s upcoming 250 year anniversary.

Unfortunately, as many of you might remember, the occasion of Balboa Park’s Centennial in 2015 was not celebrated with the fanfare that would have been appropriate.

I do hope that behind the scenes serious plans are being made for the appropriate celebration of San Diego’s 250th birthday! Or that plans will be made!

Just a thought from a silly blogger who loves San Diego!

UPDATE!

The City of San Diego has created a website dedicated to its 250th Anniversary. It lists several events that commemorate this special year. Visit the website here!

Walk up to the top of Presidio Park from Old Town and you’ll discover a variety of fascinating, historical sights. Possibly the most amazing, apart from the impressive Serra Museum building, are two extraordinary bronze sculptures, The Indian and The Padre, by renowned sculptor Arthur Putnam.

The Padre was cast in 1908. The figure of a Spanish friar stands in a small, quiet space among trees, not far from the spot where Junípero Serra founded Mission San Diego de Alcalá in 1769, which began as a temporary church at the Spanish presidio. Five years later the mission would be moved a few miles east up the San Diego River to its present location.

Here are photos of The Padre which show the sculpture’s quiet beauty.

I enjoyed an amazing walk last weekend at Mission Trails Regional Park. The guided hike met under the flagpoles of the Kumeyaay Campground, and started down a pleasant nature trail at nearby Kumeyaay Lake. The hike then proceeded at a leisurely, easy pace along several trails by the San Diego River, ending up at the Old Mission Dam.

Every month, anyone can go on a variety of free interpretative nature walks at Mission Trails Regional Park. The walks are led by experienced trail guides, who point out the native flora and fauna, and relate the fascinating history of this mountainous wilderness in the city. To learn more check out the park’s website.

Please enjoy my photos and read the descriptive captions to join me on a virtual hike. Not only will you experience natural beauty, but you’ll learn a bit about early San Diego history!
